A conductive hearing loss occurs when there is a problem with the one or more of the parts of the ear that conduct sound into the inner ear. There are many potential causes of conductive hearing loss, with some causes being easier to treat than others.
If you have any questions about conductive hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist.
An audiogram shows the softest sounds a person can hear at different frequencies (pitches). The frequencies displayed on the horizontal axis of the audiogram are those most crucial to hearing and understanding conversation, with low frequencies on the left and higher frequencies on the right. Information on audiograms is encoded using symbols, each of which represents a different test condition. Audiologists present stimuli via bone and air conduction to determine the type of hearing loss.
When the outer or middle ear is blocked or damaged, bone conduction thresholds will be better than air conduction hearing levels.
Sensorineural hearing loss occurs when there is damage to the cochlea or to the auditory nerve pathways. Test method and desired patient response is determined by patient age and developmental level. As children approach age 2 ? years, VRA is no longer effective because it cannot hold the child’s interest for the duration of the test.
Preschool: At 2 ? years of age, most children learn games used in conditioned play audiometry (CPA). School-aged Children: At around age 4 years, children are ready to respond in a more adult-like manner known as a voluntary response.
Conductive hearing loss is often temporary and may be improved with medical or surgical procedures.
Assistive listening devices (ALDs) or Hearing Assistive Technology (HATS). ALDs, such as FM systems, require the person speaking to wear a microphone.
In this condition, the inner ear works, but there is a problem that keeps the brain from recognizing and interpreting sound correctly.
The ear canal, ear drum, and the tiny bones in the middle ear make up the conductive system and any hearing loss caused by a problem in one or more of these areas is called a conductive hearing loss.
Malformation of the outer or middle ear structures, a middle ear infection in which fluid accumulates behind the eardrum, abnormal bone growth in the middle ear, a hole in the eardrum, or poor Eustachian tube function may be responsible for conductive hearing loss. Antibiotics or antifungal medications are usually prescribed for ear infections, whereas surgery is usually an option for malformed or abnormal outer or middle ear structures and other physical problems. The hearing threshold is determined to be the lowest intensity (dBHL) at which multiple presentations of a frequency specific tone were detected 50% of the time. For example, the sound “sss” presents at a high frequency, while an “ooo” presents at a lower frequency.


Air conduction testing involves the use of headphones, insert earphones, or speakers to deliver sounds to the ear canal through the middle ear and into the inner ear. Conductive hearing loss is defined as air conduction thresholds greater than 15 dB (outside the normal range) with bone conduction thresholds within the normal range. Consistent, reliable behavioral threshold testing is possible with children as young as 6 months developmental age. It is due to problems with the inner ear or damage to the hair cells or nerves inside the inner ear. Cochlear implants are used when the hearing loss is too severe to be treated with hearing aids.
The person’s voice is then transmitted into the child’s hearing aids, cochlear implants, or earphones. Unlike a sensorineural hearing loss a conductive hearing loss occurs because the sound entering the ear is reduced or dampened by the obstruction; there is no damage to the delicate nerves in the inner ear. Rarely, there may be more serious causes of conductive hearing loss and these conditions, if left unidentified and untreated, may have profound medical consequences. Hearing aids are often the best answer when surgery is not possible, because they significantly improve hearing and are convenient.
The shaded region on the audiogram shows the range where most conversational speech occurs. In general, a red “O” is used to represent the right ear while a blue “X” represents the left ear. To the right is an audiogram of an individual with conductive hearing loss in the left ear.
Traditionally, the test setting involves the child and the audiologist sitting at a small table in a sound booth.
Your child’s audiologist (health care professional who specializes in hearing problems) can tell you which type of hearing loss your child has.
For someone to hear, sound signals must travel from outside the ear through the ear canal and eardrum into the inner ear.
If fluid buildup behind the eardrum is the cause, a tiny tube may be inserted into the eardrum to help drain the fluid. Assistive listening devices allow the child to hear the person speaking without distracting background noise.
To hear words correctly, the brain must recognize and interpret the sounds that are sent to the brain.
Your child's audiologist (a health care professional who specializes in hearing problems) can tell you which type of hearing disorder your child has. A conductive hearing loss can often be partially or completely reversed with medical intervention.
Though usually not necessary, implantable hearing devices such as a bone-anchored hearing aid are an excellent alternative if neither surgery nor a traditional hearing aid are feasible options. In bone conduction testing a bone oscillator is placed behind the ear on the mastoid bone to deliver sounds directly to the inner ear by vibration, bypassing the outer and middle ear.


Notice that air conduction results show a moderate hearing loss while bone conduction results show that the cochlea and sensorineural pathway are responding within the range of normal hearing sensitivity. The child is trained to respond to a stimulus by performing a task such as putting block in a bucket or a peg in a board. These vibrations travel to the inner ear where tiny “hair cells” (cilia) and the hearing nerve turn the vibrations into nerve impulses (signals). Conductive hearing loss results when sound becomes partially or fully blocked in the outer or middle ear. Your health care provider can tell you more about what’s causing your child’s hearing loss and how it can be treated or managed. The brain then senses what we “hear.” With sensorineural hearing loss, the hair cells or nerves are damaged and do not send the signals needed for hearing to the brain. FM systems can be used in classrooms to help children with hearing loss hear their teachers. With APD, something keeps the brain from properly processing or interpreting the sounds that make up a word or words.
Normal hearing is defined as having threshold at an intensity greater than or equal to 15dB HL. Comparing air conduction and bone conduction thresholds helps determine whether a hearing loss is classified conductive, sensorineural, or mixed. In a sound-treated room, an audiologist can quickly train a child to look towards something interesting like a puppet or video when a sound is heard (i.e.
Scientists think it may be related to problems with the hearing nerve, but more research needs to be done. There are hearing tests available to check for ANSD that can be done by your child's audiologist. With hearing loss, either a temporary blockage or a permanent problem within the ear or brain keeps sound from being heard or understood. In cases where a child will not or cannot wear earphones for ear-specific threshold testing, sounds may be presented via speakers (in the “soundfield”). This technique enables audiologists to draw general conclusions about a child’s hearing but does not give any ear-specific information.
Arrows connected to audiogram symbols indicate a no response value, indicating that at the specified frequency no response was detected. The Guidelines for Audiometric Symbols can be found on the website of the American Speech-Language-Hearing Association (ASHA).
