Decoding Sound: What is an Audiogram and its Importance in Diagnosing Hearing Loss?

The sense of hearing is a treasured gift for every human being. Devoid of hearing power, human beings will fail to connect with the whole world around them. It is through hearing that people get to appreciate music, engage in conversations, and stay connected to the environment. However, not every person gets to enjoy the joy of hearing. Quite a lot of people undergo severe hearing concerns and the continuation of hearing loss gradually diminishes this essential sense. Understanding hearing loss is the first step in treating it, and the audiogram is a very reasonable tool for this process. We shall explore the realm of audiograms in this post, outlining their definition, method of operation, and significance in the identification and treatment of hearing loss.

What Exactly is an Audiogram?

An audiogram can be defined as a visual representation of a human being’s capacity to perceive sounds at diverse frequencies and intensities. This is generally depicted as a graph with frequency counted on the horizontal axis (from low to high frequencies) and intensity or loudness calculated on the vertical axis (from soft to loud sounds). The outcomes of an audiogram are acquired through a hearing test, achieved by an audiologist or hearing professional.

During an audiogram test, the individual listens to a series of pure tones or speech stimuli at distinct frequencies and volumes. While on the go, they indicate when they are able to hear the sounds, and the outcomes are recorded on the audiogram.


1. Hearing Threshold

The outcomes are displayed as a series of symbols, generally o’s (circles) or x’s (crosses), on the graph. Each symbol denotes the mildest sound a person can perceive at a certain frequency. When the symbols are near the top of the graph, this indicates the individual’s hardship in hearing that particular sound.

2. Audiometric Frequencies

On the horizontal axis, frequencies are expressed in Hertz (Hz), and they normally range from 250 Hz (low-pitched noises) to 8000 Hz (high-pitched sounds). To determine which auditory system components are impacted, an audiogram's measured frequencies are crucial.

3. Ear-Specific Results

Audiograms give medical practitioners individual results for each ear, making it possible to see any differences in hearing loss between the ears. When diagnosing different types of hearing impairments, this can be crucial.

4. Speech Audiometry

Certain audiograms incorporate speech audiometry in addition to pure-tone audiometry. This evaluates a person's capacity to comprehend and repeat spoken phrases at different volumes.

Significance of Audiogram in Diagnosing Hearing Loss

Audiograms are necessary for various reasons. Let us check them out.

1. Diagnosis

They serve as the main diagnostic instrument for hearing loss early intervention and help select the correct treatment approach. They enable customized treatment regimens by assisting medical practitioners in identifying the kind, extent, and configuration of hearing loss.

2. Treatment Planning

Audiograms assist in identifying the best course of action for treatment adhering to the severity of the patient. The outcomes help medical practitioners determine the best course of action, whether cochlear implants, hearing aids, or other procedures.

3. Tracking Progress

For patients receiving hearing loss treatment, audiograms are a crucial tool for assessing cochlear implant surgery recovery pace, or in general, the recovery pace of the therapies. They enable modifications as necessary and aid in tracking advancements over time.


4. Educational and Legal Purposes

Audiograms are frequently utilized in educational backdrops to decide the requirement for accommodations. Apart from that, they are equally important for legal matters like worker’s compensation claims related to hearing loss caused by occupational exposure to loud noise.

5. Communication Strategies

Audiograms assist audiologists and patients in analyzing the particular frequencies and sounds impacted by hearing loss. With the help of this information, communication strategies can be developed that will cater to the patient’s demands.

Neubio’s Advanced Cochlear Implant Addressing Severe Hearing Loss

People who suffer from severe to profound hearing loss now have hope and that is a cochlear implant - a result of incredible improvements in hearing technology in recent years. One significant participant in this space is Neubio, a forward-thinking business that changed the way we treat hearing loss by introducing a progressive cochlear implant device.

For many people with substantial hearing loss, traditional cochlear implants have been a game-changer. They do, however, have certain limits, notably when it comes to hearing and understanding speech, especially in loud settings. Neubio has developed a state-of-the-art cochlear implant system that combines cutting-edge technology with a thorough comprehension of auditory processing in order to address these issues.

In summary, the audiogram is a vital instrument in the area of audiology that offers vital data for the identification and management of hearing loss. Manufacturers like Neubio are pushing the limits of what is feasible in hearing restoration acknowledging the technological and innovative breakthroughs. With this progressive cochlear implant, people with severe to profound hearing loss can finally experience the beauty of sound and have access to a world full of sounds. We can anticipate a time when hearing loss will no longer be a hindrance but rather a bridge to a more satisfying auditory experience as we continue to unravel the secrets of hearing.
