Also referred to as noise-induced hearing loss, sensorineural hearing loss is caused by damaged or destroyed hair cells in the inner ear that no longer transfer sound information to the brain.
Sensorineural hearing loss can rarely be corrected medically or surgically, so hearing aids are the primary solution.
Since sensorineural hearing loss is typically caused by exposure to loud noises, we highly recommend the use of ear protection if you find yourself around loud noises frequently.
If you have any questions about sensorineural 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. For example, the audiogram on the left depicts a symmetrical hearing loss and the audiogram on the right depicts an assymetrical hearing loss. Sensorineural hearing loss refers to any reduction in hearing sensitivity or sound clarity that is caused by damage to the delicate structures of the inner ear or the nerve pathways that carry the sound signal from the inner ear to the auditory processing area of the brain. Hearing aids are the primary treatment for sensorineural hearing loss as medical or surgical intervention is rarely possible.

Since sensorineural hearing loss is often caused by exposure to loud noises, we highly recommend the use of hearing protection if you find yourself around loud noises frequently. If you have any questions about sensorineural hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist. Hearing loss of this sort is often caused by prolonged exposure to very loud noise, though auditory pathways (or hair cells that transfer sound) in the brain are sometimes abnormal at birth, resulting in some level of hearing loss. Correctly fitted hearing aids amplify tones based on an individual’s unique sound deficiencies. 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. Unilateral means hearing loss in one ear, with normal hearing sensitvity in the other ear.
Sensorineural hearing loss is the most common type of hearing loss and affects 28 million Americans. Exposure to very loud noise is the most common cause of sensorineural hearing loss followed by aging (presbycusis).
Correctly fitted hearing aids stimulate the affected nerves in the inner ear and fill in the Sound Voids that most sufferers experience. Typically, sensorineural hearing loss reduces the ability to hear faint sounds or causes speech to sound faint or muffled, which results in the need for sound amplification. In most cases, total communication is greatly improved through the addition of hearing aids. 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. Certain medications and health conditions such as diabetes and heart disease are also known causes of sensorineural hearing loss. Today’s hearing aid technology can even address ‘high-frequency’ sensorineural hearing losses that were once thought to be un-treatable. A healthy diet and regular exercise are a must to prevent the onset of heart disease and other medical problems that are also identified with hearing loss. 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. 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. 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).
