How to Analyze and Interpret Audiometric Test Results taken from Industrial Settings

Preserving workers' auditory health is of paramount importance. This necessitates regular audiometric testing to monitor and safeguard employees' hearing capabilities. But how do we make sense of the data generated by these tests? In this blog, we delve into the world of interpreting workers' audiograms, exploring the nuances of audiometric testing and comparing traditional methods of result interpretation with modern approaches.

The Basics of an Audiogram

An audiogram is a visual representation of a person's hearing ability. It maps the softest sounds a person can hear at various frequencies and is usually presented in a graph format. The horizontal axis represents different frequencies, while the vertical axis indicates sound intensity or volume, typically measured in decibels (dB). Together, these axes compose a symphony of auditory perception, portraying the delicate balance between different pitches and their corresponding loudness levels.

Audiograms Key Components

• Frequency (Hz): Frequencies are displayed along the horizontal axis, ranging from low to high pitches. The lowest frequencies are on the left (e.g., 250 Hz), and the highest frequencies are on the right (e.g., 8000 Hz).
• Intensity (dB): Intensity is plotted along the vertical axis, reflecting the loudness level at which a person can hear a specific frequency. The higher up on the graph a symbol is placed, the louder the sound needed for the individual to hear it.
• ‍Thresholds: Audiograms display hearing thresholds at different frequencies. Normal hearing thresholds fall within the range of 0 to 25 dB. Any deviations from this range could indicate potential hearing issues.
• Degrees of Hearing Loss: Hearing loss is categorized into degrees, such as mild, moderate, severe, and profound. Interpreting the severity of hearing loss based on the audiogram assists in determining appropriate interventions and safety measures.
• Notch Patterns: In cases of noise-induced hearing loss, audiograms might exhibit a characteristic notch pattern, with greater loss at specific frequencies. Identifying these patterns can help trace the cause of the impairment.

Interpreting Audiogram Results

Understanding the patterns presented in an audiogram is crucial for accurate interpretation. There are distinct shapes that audiologists look for:

• Normal Hearing (0-25 dB): If the symbols fall within the 0-25 dB range, the person has normal hearing for those frequencies. They can hear soft sounds and speech clearly in typical environments.
• Mild Hearing Loss (26-40 dB): Symbols above 25 dB but below 40 dB indicate mild hearing loss. Individuals might struggle to catch soft speech, especially in noisy surroundings.
• Moderate Hearing Loss (41-55 dB): Symbols in this range signify moderate hearing loss. Understanding speech, particularly in noisy settings, becomes challenging.
• Moderately Severe Hearing Loss (56-70 dB): Hearing loss in this range is considered moderately severe. Louder speech is audible, but communication difficulties are significant.
• Severe Hearing Loss (71-90 dB): Symbols falling within this range represent severe hearing loss. Individuals might rely heavily on visual cues and louder sounds for communication.
• Profound Hearing Loss (91+ dB): When symbols surpass 90 dB, the hearing loss is profound. Understanding speech without amplification is nearly impossible.

The Traditional Approach on Audiogram Results

In the past, interpreting audiograms was a complex endeavor that required specialized training. Audiologists followed a manual process, assessing the audiogram's shape and comparing it to standardized patterns to determine the type and severity of hearing loss. This approach, while effective, was time-consuming and left room for human error.
