In the initial meeting with an audiologist, there may be a sense of apprehension. Following a hearing test, the audiologist will guide you through a visual representation, explaining the chart’s indicators and symbols to ensure a thorough understanding of the results. Despite the initial complexity of the audiogram, familiarizing oneself with the related terminology facilitates a more seamless navigation and interpretation. This knowledge not only enhances communication with your audiologist but also provides a clearer insight into one’s hearing capabilities. With the assistance of the audiologist, individuals can gain an understanding of a hearing test and their hearing loss and discuss appropriate next steps, including the potential need for a hearing aid.
Understanding a Hearing Test: Frequencies and Beyond
An audiogram is a visual representation that delineates volume on the vertical axis and frequency on the horizontal axis. The vertical axis is quantified in decibels (dB). As the line ascends, the sound volume diminishes. The sound becomes barely perceptible at the uppermost point, which registers at zero decibels (dB). Progressing downward, the sound becomes progressively louder, reaching 100 dB. The horizontal axis is measured in hertz (Hz) and encompasses the range of 250 Hz to 8,000 Hz. Lower frequency sounds typically encompass vowel sounds, while notably higher frequencies characterize consonants.
Assessing the Audiogram
Please remember the following information: When interpreting the graph, your audiologist will provide guidance to ensure comprehension. You will commence at the top left corner of the graph, denoting the lowest frequency. Your audiologist will initiate the process by playing a sound at the lowest decibel level. Following your perception of the sound, they will mark 125 Hz and zero decibels. If you are unable to perceive the noise, an increased volume will be utilized. This process will continue until marks appear on the horizontal axis.
The Results of the Audiogram
Normal hearing encompasses the ability to detect a wide range of frequencies. The ability to perceive all sounds at 25 dB is typical for individuals with normal hearing. However, if an individual can only pick up a sound at 40 dB, it may indicate moderate hearing loss at that specific frequency. Following your hearing test, your audiologist will assess your results and elucidate the level of hearing loss, if present. If you wish to review your results for a more comprehensive understanding of your hearing loss, you may request a copy from your audiologist. The ranges of hearing loss are categorized as follows:
• Normal hearing is 0-25 dB
• Mild hearing loss is 20-40 dB
• Moderate hearing loss is 40-70 dB
• Severe hearing loss is 70-90 dB
• Profound hearing loss of above 90 dB
Once you have thoroughly understood your hearing loss and what to expect during your hearing appointment, you can make the most of the experience. Depending on the level of your hearing loss, your audiologist might recommend hearing aids.

Frequently Asked Questions
An audiogram is a chart that displays hearing ability by plotting sound volume (in decibels) on the vertical axis and sound frequency (in hertz) on the horizontal axis. It helps visualize the softest sounds a person can hear at various frequencies, ranging from low to high. This visual guide allows the audiologist and patient to understand the range and degree of hearing loss if present.
The vertical axis measures volume in decibels (dB), starting at 0 dB for very soft sounds and increasing downward to 100 dB for louder sounds. The horizontal axis measures frequency in hertz (Hz), from 250 Hz to 8,000 Hz, covering low to high pitched sounds. Lower frequencies correspond to vowel sounds, and higher frequencies relate to consonants. Together, these scales help identify at what loudness and pitch a person can hear.
Hearing loss severity is classified by decibel thresholds: normal hearing ranges from 0-25 dB, mild hearing loss is 20-40 dB, moderate is 40-70 dB, severe is 70-90 dB, and profound hearing loss is above 90 dB. These ranges help your audiologist determine the extent of hearing impairment at specific frequencies shown on the audiogram.
During the hearing test, the audiologist plays sounds at different volumes and frequencies. They start at the lowest frequency and volume, gradually increasing the decibel level until you can hear the sound. Each audible response is marked on the audiogram, allowing a complete map of your hearing sensitivity across the tested frequencies. This guided process ensures accurate interpretation of your hearing ability.
Yes, you can request a copy of your audiogram from your audiologist after the hearing test. Having a copy helps you better understand your hearing health, track changes over time, and discuss your results more effectively with healthcare providers or family members.
Based on the severity and type of your hearing loss determined from the audiogram, your audiologist may recommend options such as hearing aids or other hearing assistance devices. Early intervention can improve communication and quality of life, so discussing these recommendations is an important step after your hearing assessment.
Understanding the audiogram and related terminology helps you communicate more effectively with your audiologist, follow their recommendations confidently, and better comprehend your own hearing abilities and challenges. This knowledge empowers you to make informed decisions about your hearing health and next steps.
