An audiogram is a graph that shows the results of a hearing test. It plots how well you can hear different frequencies, which are the highness or lowness of sounds, and at what volume, or intensity, those sounds need to be for you to detect them. The horizontal axis represents frequency in Hertz (Hz), typically ranging from 250 Hz (low pitch, like a bass drum) to 8000 Hz (high pitch, like a bird chirping). The vertical axis represents intensity in decibels (dB HL), with 0 dB HL being the softest sound a young, healthy ear can typically hear, and higher numbers indicating louder sounds.

When you undergo a hearing test, sounds are presented to you at various frequencies, and you indicate when you can hear them. These results are plotted on the audiogram. Typically, the audiologist will use different symbols to represent the results for each ear. For example, an "X" might represent the right ear and an "O" might represent the left ear. Air conduction thresholds, which measure how well sound travels through the outer and middle ear to the inner ear, are usually plotted first. Bone conduction thresholds, which bypass the outer and middle ear to directly stimulate the inner ear, may also be measured to help determine the type of hearing loss.

The degree of hearing loss is determined by the average of your hearing thresholds across key frequencies. Mild hearing loss might mean you have difficulty hearing soft speech or sounds in noisy environments. Moderate hearing loss can make it challenging to understand normal conversation without a hearing aid. Severe hearing loss means you can only hear very loud sounds and will likely need significant amplification. Profound hearing loss indicates that you can only hear extremely loud sounds, and even with amplification, understanding speech can be very difficult.

The audiogram also helps identify the type of hearing loss. Conductive hearing loss occurs when there is a problem in the outer or middle ear, preventing sound from being conducted effectively to the inner ear. Sensorineural hearing loss is caused by damage to the inner ear (cochlea) or the auditory nerve. Mixed hearing loss is a combination of both conductive and sensorineural components. The pattern of the plotted results on the audiogram provides clues to the audiologist about the location and nature of the hearing impairment.

understanding my audiogram your audiogram is crucial for managing your hearing health. It provides a clear picture of your hearing capabilities and helps your audiologist recommend the most appropriate interventions, such as hearing aids, assistive listening devices, or further medical evaluation. Regular audiograms can also track changes in your hearing over time, allowing for timely adjustments to your management plan. It's a vital tool for both diagnosis and ongoing care.
