When you're a family member coping with the hearing loss of a loved one, you may encounter frustration, the feeling of being ignored, separation from the relationship and isolation from daily family life.
When a family member has a hearing loss, treated or untreated, the loss impacts the entire family and communication skills are put to the test. DiMarco uses the universal language of dance to change the hearing world’s perception of what it means to be Deaf – and he just might win the Mirrorball trophy in the process. Hearing ability is important for children to develop speech and language skills as they grow. Unfortunately, hearing loss is becoming more commonplace in youth due to the noise in our environment. There are several possible causes for hearing loss in children, whether it's congenital or acquired.
Birth complications, including the presence of herpes, rubella cytomegalovirus, toxoplasmosis or another serious infection, lack of oxygen or the requirement of a blood transfusion for some reason. The mother had an infection during pregnancy, including things like toxoplasmosis, cytomegolavirus, herpes simplex or German measles.
Experts agree that genetic factors cause more than 50 percent of all hearing loss in children, whether present at birth or developed later in life.
Autosomal recessive hearing loss - This is the most common type of genetic congenital hearing loss - autosomal recessive accounts for around 70 percent of all genetic hearing loss cases. Autosomal dominant hearing loss - This type of hearing loss accounts for around 15 percent of genetic hearing losses, according to the American Speech-Language-Hearing Association (ASHA). Genetic syndromes - These include Usher syndrome, Treacher Collins syndrome, Waardenburg syndrome, Down syndrome, Crouzon syndrome and Alport syndrome. You might have noticed that the percentages don't add up to 100 for genetic and non-genetic causes of congenital hearing loss. Transient or fluctuating hearing loss in children is also detrimental to speech and language development. Transient hearing loss due to an ear infection can occur when fluid inhibits the vibrations of the tiny middle ear bones, making efficient sound transmission difficult. As mentioned above, hospitals routinely perform hearing screening on infants in the first 24-48 hours after birth. One way to determine if your child’s hearing is developing appropriately is by monitoring important speech and hearing milestones, such as those listed below from ASHA. Audiologists can perform in-depth behavioral hearing examinations for even very young children (as young as 6 months) who cannot participate in traditional testing procedures. Hearing aids are just one kind of device that can help children with hearing loss hear clearly again.
Cochlear implants are surgically implanted devices that directly stimulate the auditory nerve in the inner ear with electrical stimulation.
For children who have had hearing loss that has affected their speech, he or she might need speech-language therapy after getting hearing aids or a cochlear implant to help him or her catch up on speech delays. Many hearing aid manufacturing companies offer assistive listening devices that are discreet and work well in a classroom situation in conjunction with the child's hearing aid or cochlear implant.

Congenital conductive hearing loss may occur for reasons of atresia or middle ear anomalies such as a fused malleus and incus, or fixation of the stapes. In the current case study, we investigated the effects of long-term congenital, unilateral mixed (conductive and sensorineural) hearing loss on sound localization, speech understanding, and cortical organization, both before and after the conductive component of the hearing loss was corrected in adulthood.
Written informed consent was obtained from the participant in accordance with the Declaration of Helsinki and guidelines approved by the Human Research Protection Office at Washington University School of Medicine (WUSM). The participant (P1) was a 41 year old female who had a history of unilateral hearing loss in the right ear that had been present since early childhood (probably since birth).
Pre-operative, high resolution CT scanning revealed a slightly thickened stapes footplate with no other abnormalities suggestive of otosclerosis. All testing occurred in double-walled sound booths with the participant comfortably seated. An adaptive speech reception threshold (SRT) psychoacoustic task resulted in speech thresholds for quiet and nine competing noise conditions (modified from the task described in Litovsky (2005) and Johnstone and Litovsky (2006)). A psychoacoustic measure determined the random spectrogram sound (RSS) that was most different from two others during each trial.
Previously described protocols (Burton et al., 2012, 2013) were used to perform functional magnetic resonance imaging (fMRI), preprocess the images, and analyze blood oxygen level-dependent (BOLD) responses to auditory stimulation of the unaffected left ear. The distribution of volume-based F-Zstats from each imaging session was superimposed on coronal slices through the patient’s brain. Figure 3 displays results for R-Space sentence understanding in the presence of restaurant noise. The Hearing Assessment Clinic is one of the leading independent veterinary hearing test centres in the United Kingdom. The clinic provides detailed hearing test and analysis services for dogs and cats of all breeds, using the Brainstem Auditory Evoked Response (BAER) technique. BreedersBreeders can significantly reduce the number of dogs and cats born deaf by only using dogs and cats who have passed the BAER test.
Pet OwnersKnowing that their dog has a hearing loss is important, as owners can utilise different techniques e.g. Trainersneed working dogs with "normal" hearing so that they can perform their work effectively. The BAER test can tell you if your dog or cat has hearing loss, which ear is affected, the location and the severity of the disorder. Please note that the NHS does not give any indication of the functionality of the auditory nerve or the auditory processing.
If the Newborn Hearing Screening shows irregularities, it might be an indication of a hearing disorder. If the rescreening still shows irregularities, the baby needs to see a pedaudiologist for further audiometry (hearing diagnostics). In the past, hearing loss in children often went undetected until the child was around two years old, when it became obvious that he or she wasn't talking yet. In 2013, the CDC estimated at least 12.5 percent of children and adolescents ages six to 19 have suffered permanent damage to their hearing due to excessive noise exposure. There are various causes of congenital hearing loss, though they are not always easily identified. Babies that have a birth weight of less than 3 pounds or that require certain life-sustaining drugs for respiration due to prematurity are at risk for hearing loss. Ototoxic medications are not usually illicit substances - medications like various antibiotics and NSAIDS can potentially cause damage to the auditory nerve or other hearing structures of the fetus. However, non-genetic factors account for only around 25 percent of congenital hearing loss. What this means is that neither parent has a hearing loss, but each parent carries a recessive gene that gets passed to the child. In autosomal dominant hearing loss, one parent carrying a dominant gene for hearing loss passes it to the offspring.
This is because some of the time, doctors are not sure why an infant is born with a hearing loss.
Transient hearing loss can be caused by otitis media, more commonly known as middle ear infection.
If an infant fails the initial screening, he or she is usually scheduled for a second screening a few weeks later. If a child has wax buildup, an ear infection or another problem causing temporary hearing loss, the audiologist will take care of the problem or refer you to an otolaryngologist (ear, nose and throat physician) to have the temporary hearing obstruction treated. There are several objective tests that infants, toddlers and young children can undergo as well. There are various advanced models today that offer high-quality hearing assistance, as well as coverings and other devices to ensure that young children don't remove or misplace their hearing aids. Cochlear implants also have an external device, and many companies make kid-friendly devices that can be held on with a soft headband.

Essentially, the teacher wears or has a discreet microphone in front of him or her that transmits his or her voice directly to the child's hearing aids or cochlear implant.

This occurs in cases of unilateral sensorineural hearing loss, where there is sensory (inner ear) or neural dysfunction, as well as losses in the conductive pathway between the outer and inner ear. For example, UCHL created by plugging one ear in young owls initially altered localization abilities but abilities then recovered, that is, the owls made use of abnormal cues to accurately localize (Knudsen et al., 1984a,b).
Degree of hearing loss and the presence or absence of other inner ear deficits varies with the abnormality, but can result in 60 dB of hearing loss from the conductive aspect alone.
Measures included interaural temporal difference limens, MLDs, sound localization and speech recognition in noise. Family history included a father and paternal grandmother with mixed unilateral hearing loss.
The participant underwent a laser stapedotomy procedure with prosthetic reconstruction completed under general anesthesia through an aural speculum.
All test stimuli were from recordings and individually calibrated for the presentation equipment. SRT determinations were for test spondees (two-syllable words with equal stress on both syllables) spoken by a male talker and always presented from a loudspeaker facing the front of the seated participant. BOLD responses to RSS stimuli of 2 s duration were recorded at three times: pre-surgery and at 3 and 9 months post-surgery.
Additionally, BOLD response time courses were extracted from regions of interest for peak F-Zstats identified with an automated search (Kerr et al., 2004). For each plot, the location of the loudspeaker source (in degrees azimuth) is indicated along the x-axis and of the reported loudspeaker along the y-axis. If tested prior to training, those affected can be removed from the training program, saving the trainer time, money and stress. From this information, either treatment can be performed to cure or improve the hearing loss, or advice given regarding training and management.
They may be difficult to train and some with partial deafness may have problems localising sounds.
As functional hearing is decisive for the mental, emotional and social development of children, it is crucial to discover congenital hearing loss as early as possible. However, these kinds of dysfunctions are very seldom and usually occur in concurrence with other diseases. Nevertheless, if you as a parent or caregiver have the slightest impression that your child suffers from a hearing loss, don’t hesitate to contact a pedaudiologist or a clinic for a reliable diagnosis. Research has demonstrated that detection and intervention for hearing loss prior to six months of age results in significantly better outcomes than intervention after six months of age. It's important that parents, caretakers, physicians, teachers and others know the signs of and address hearing loss in children because early hearing loss - especially that which is undiagnosed - can cause significant development and emotional problems for children that have long-lasting effects. Experts agree that genetic factors - meaning the hearing loss is hereditary - cause more than 50 percent of all hearing loss in children, whether the loss is present at birth or manifests later in life. Parents are usually surprised when their child is born with this type of hearing loss because people typically aren't even aware they have the recessive gene.
This parent may or may not have hearing loss, but he or she might have other symptoms or signs of a genetic syndrome. At least 75 percent of children have had one episode of otitis media by the time they are three years old. However, frequent, untreated middle ear infections can cause cumulative damage to the bones, eardrum or auditory nerve, creating a permanent, sensorineural hearing loss.
However, sometimes infants who pass the hearing screening at birth may exhibit signs of hearing loss as they age. There are several models of devices to choose from, including behind-the-ear hearing aids or those that are almost entirely in the ear canal and very discreet.
In animals, unilateral conductive hearing loss (UCHL) results in structural and functional changes within the auditory system. Self-assessment questionnaires that probe hearing in different listening environments indicated numerous hearing difficulties in those with congenital UCHL (Priwin et al., 2007).
After the earplug was removed, these owls again made localization errors but after some weeks they regained accuracy.
However, in a later longitudinal study of adults with otosclerosis, MLDs returned to normal in many participants when tested a year after hearing restoration (Hall and Grose, 1993).
Post-surgery binaural improvements were significant for some individuals and some tasks but not all; sound localization and speech recognition continued to be difficult especially when noise was towards the NH ear and the restored ear was relied upon for speech understanding.
P1’s father had successful stapes surgery in adulthood as a treatment for otosclerosis induced hearing loss.
This procedure is designed to restore mobility to the middle ear bones for improved sound conduction. All loudspeakers presented a recording of diffuse restaurant noise (60 dB SPL), replicating a challenging real-life listening situation.
Spectral RSS differed by dividing the bandwidth into 3–16 spectral bands and changing between bands at a fixed temporal rate of 3 Hz. The Speech domain probes speech recognition in a variety of listening environments and a range of talker visibility. Presentation times for RSS stimuli varied during 9-s silent intervals in 11-s volume acquisitions, which enabled capture of BOLD at different stimulus delays with respect to the echo-planar images (EPI) in this interrupted single event design (Belin et al., 1999).
Note that the 9-month results were equivalent.) As expected, thresholds for the NH or left ear (blue symbols) were unchanged compared to pre-surgical results.
Means and standard deviations of reported loudspeakers are plotted for each source loudspeaker location for pre-surgery and post-surgery test intervals of 3 and 9 months, respectively in Panels A to C.
By determining the location and severity of the hearing disorder, medical or surgical treatment may be used effectively to restore hearing, or an appropriate management plan employed. These include the Dalmatian (21%) , English Setter, Border Collie Bull Terrier, Australian Cattle Dog and Cavalier King Charles Spaniel. Newborn Hearing Screening (abbreviated NHS), sometimes also called infant hearing screening, is usually done some days after birth prior to hospital discharge.
Most of the test equipment used in NHS provides an automated workflow and can easily be handled by non-experts. If the test has been conducted within the first three days after birth, tissue from the mother’s womb or amniotic fluid might still occlude the ear canal. As a result, newborn hearing screening has become universal in hospitals across the United States and children with hearing loss are being identified and treated at much younger ages. This type of infection is very common in children because of the Eustachian tube position during childhood. If you think your child is having difficulty hearing you, visit your pediatrician right away. After exam, the audiologist will spend time talking with you about your child's hearing ability and recommend an appropriate treatment plan or medical intervention. We investigated effects of long-term congenital unilateral hearing loss on localization, speech understanding, and cortical organization following hearing recovery. For example, on the UCHL side in rats, the size of neurons in the anteroventral cochlear nucleus was smaller (Coleman and O’Connor, 1979) and binaural interactions were absent in the inferior colliculus (Silverman and Clopton, 1977). However, localization performance did not recover when ear plugging occurred in older owls or even in younger owls when the plug remained in place beyond a few weeks. Otosclerosis is typically diagnosed in young to middle adulthood and the hearing loss is often progressive in nature (and primarily conductive), thus these individuals had several years of normal hearing (NH) prior to hearing loss onset. When left untreated into adulthood, individuals will have extended periods of auditory deprivation. Abnormal auditory experience in early life may affect later binaural abilities; however, the nature and impact of these interactions are not entirely clear.

P1 and her family had believed P1’s hearing loss to be sensorineural and non-correctable. Air-conduction thresholds via TDH headphones (Panel A) or insert earphones (Panel B) are indicated with blue Xs for the left ear and red triangles or circles for the right ear. The participant sat approximately three feet in front of the center loudspeaker, was unaware that five loudspeakers were inactive (#2, 4, 8, 12, 14), and was instructed to face the center loudspeaker between each presentation but was allowed head turns during each carrier-word presentation.
Two 20 sentence lists were administered and an average signal-to-noise ratio (SNR) for 50% accuracy (SNR-50) obtained.
There were three noise types: multi-talker babble (MTB) and two types of single-talker noise (a female talker and a male talker each presenting Harvard IEEE sentences). Temporal RSS differed by changing between three spectral bands at temporal rates between 8 and 30 Hz. Subsequent assembly of BOLD amplitudes relative to baseline (% change in response) at stimulus delays from 2 to 9 s prior to the EPI reconstructed an average BOLD response time course. Thus, the analyses evaluated activity in core primary auditory (Te1), planum temporale (Te2), and planum polare (Te3).
The red line connects post-surgical air-conduction thresholds (obtained with insert earphones having approximately 75–90 dB interaural attenuation). Correct identification of all presentations results in a straight diagonal line from the lower left- to the upper right corner.
The y-axis shows the possible reported response loudspeaker locations in degrees azimuth that range from −70 degrees toward the NH ear side at the bottom of the axis to +70 degrees toward the hearing-impaired ear side at the top of the axis. Pre-surgery, P1 had 50% accuracy for sentences presented 3.5 dB softer than the surrounding restaurant noise (60 dB SPL). The test routine takes only a few minutes and can be done while the baby is asleep or quiet.
The company operates as a subsidiary of Siemens Audiologische Technik GmbH, Germany and a partner of. The Eustachian tube, which allows for air pressure equalization between the middle ear and the nasopharynx, is smaller and more horizontal during development. Hearing in the congenitally affected ear of a 41 year old female improved significantly after stapedotomy and reconstruction. Likewise in cats, UCHL reduced the inhibition from the ipsilateral ear on neurons in the inferior colliculus when the contralateral ear was deprived of sound (Moore and Irvine, 1981). Thus, the ability to recover was affected by the age at which UCHL occurred as well as the age at which hearing was restored. A hearing aid was fitted around age 5 but discontinued after a brief trial due to lack of benefit.
Circles indicate unmasked right ear thresholds and triangles indicate thresholds obtained with masking noise presented to the better hearing left ear. The malleus and incus were mobile and the stapes firmly fixed in the oval window consistent with a congenitally fixed stapes.
Head turns were allowed since it more accurately simulates talker localization in conversational settings. Sentences were presented from the front loudspeaker beginning at a +6 dB SNR and adapted to be easier or more difficult based on the participant’s responses.
Spectral RSS had greater complexity with more spectral bands and temporal RSS were more complex with higher temporal rates. In the Qualities domain, respondents indicate sound naturalness, listening effort and the ability to segregate multiple sounds. Open circles indicate unmasked thresholds and open triangles indicate thresholds obtained with the unaffected ear masked.
Symbols indicate mean responses for each active sound-source location and error bars represent ±1 standard deviation.
By 9 months post-surgery, P1 was able to understand sentences at even softer levels (4.9 dB softer than the restaurant noise). A dog may be born deaf (congenital deafness), or it develop a hearing loss in later life (acquired deafness).
Pre-operative hearing threshold levels showed unilateral, mixed, moderately-severe to profound hearing loss. Additionally, UCHL leads to decreased 2-deoxyglucose uptake bilaterally in the higher auditory medial and lateral superior olive nuclei even in silence, indicating decreased neuronal activity (Tucci et al., 2001).
While it is well known that unilateral deprivation of the visual system early in life results in permanent impairment of binocular vision (Hubel and Wiesel, 1970), less is known about the developing auditory system’s ability to recover binaural abilities. In adulthood, the participant had a comprehensive audiological evaluation that diagnosed the loss as mixed.
Masked bone-conduction thresholds for the right ear are indicated with red left-facing brackets. A CO2 laser was used to make a stapedotomy in the center of the stapes footplate and a Teflon piston was placed and connected to the incus. After each presentation, the participant repeated the word and indicated the source speaker number.
A four-alternative forced-choice task, without feedback, determined subsequent presentation levels that continued through four reversals using an adaptive paradigm based on participant responses.
Separately for each imaging session, F-tests per voxel evaluated whether the variance of evoked BOLD responses was greater than variance due to baseline noise. Whatever the reason, the result needs to be taken seriously and will lead to a rescreening 2-3 weeks afterwards. Interestingly, in a number of these studies, bilateral conductive hearing loss had little to no effect on neuronal size or binaural interactions, with normal maintenance of contralateral and ipsilateral projections. Undefined in humans is a sensitive period for binaural hearing, where behavior can adapt to abnormal experience and develop accurate abilities, and a critical period, after which the ability to adapt to altered (including restored) hearing is greatly diminished or nonexistent.
For localization, a root mean square (RMS) error score was calculated as the mean target-response difference, irrespective of error direction.
Together, these studies suggest that modifications in the balance of afferent activity alter binaural interactions and auditory system structures. The manipulated variable was minimum detectable changes (JND) in spectral or temporal complexity. Measurements were of sound localization with intensity-roved stimuli and speech recognition in various noise conditions. The difference between the air- and bone-conduction thresholds identifies the conductive component of the participant’s hearing loss, that is, the portion of the loss that could potentially be corrected through surgery.
Activation magnitudes were determined in core, belt, and parabelt auditory cortex regions via an interrupted single event design.
Hearing levels were normal in the unaffected left ear (blue symbols) resulting in a large hearing asymmetry between ears.
Feedback was provided for correct responses and each of four test runs concluded with eight reversals.
Hearing improvement following 40 years of congenital unilateral hearing loss resulted in substantially improved sound localization and speech recognition in noise.
With this level of asymmetry and the mixed nature of the hearing loss in the affected ear, audiological masking approaches become more complicated due to potential cross masking effects. Each of the JNDs for spectral and temporal RSS complexity was an average of the last four reversals. One-third octave narrow bands of masking noise (centered at the test frequency) were presented to the unaffected ear to isolate the affected ear during testing.
Contralateral auditory cortex responses were increased after hearing recovery and the extent of activated cortex was bilateral, including a greater portion of the posterior superior temporal plane. Testing was completed with TDH-49 headphones with 40–60 dB of interaural attenuation.
Thus, prolonged predominant monaural stimulation did not prevent auditory system changes consequent to restored binaural hearing. Although a 15 dB plateau was achieved at each frequency (increases in masking level at the unaffected ear did not increase the patient’s response level in the affected ear), high levels of masking noise to the unaffected ear could possibly have been detected by the cochlea of the affected ear via bone conduction while attempting to identify accurate air-conduction thresholds of the affected ear. Results support future research of unilateral auditory deprivation effects and plasticity, with consideration for length of deprivation, age at hearing correction and degree and type of hearing loss.
