Understanding High-Frequency Hearing Loss

In the picture above, our patient (name changed for privacy) shows a typical case of high-frequency hearing loss. This type of hearing loss is often caused by natural wear and tear of the delicate hair cells in the cochlea — the part of the inner ear responsible for translating sound into signals for the brain.

On the audiogram:

• Red line = right ear

• Blue line = left ear

• Vertical axis shows the quietest sound (in decibels, dB) the patient can hear.

• Horizontal axis shows the pitch or frequency of the sound.

For example:

• At 6000 Hz, the patient can only hear sounds at 90 dB in the right ear.

• At 1000 Hz, the left ear hears much better, at 30 dB.

What Counts as “Normal” Hearing?

There’s no single definition of “normal” hearing. However, to follow conversations in a group, manage background noise, or enjoy TV shows clearly, you typically need to hear at thresholds no worse than 10–15 dB across most frequencies.

How Hearing Aids Help

Hearing aids are programmed to match the patient’s audiogram. Modern digital aids sample incoming sounds — their pitch (frequency) and loudness — and then apply just the right amount of amplification.

• Half-Gain Rule: If a sound is 20 dB at 1000 Hz, the hearing aid might add about 5 dB amplification.

• Noise Reduction: Many aids automatically reduce low-frequency background noise.

• Directional Microphones: Aids can focus on sounds coming from in front, such as voices in conversation.

• Smartphone Streaming: Most modern hearing aids stream calls, music, and TV directly from your smartphone.

For example, in a noisy restaurant, the patient can use their app to adjust settings for the best possible clarity.

Why Treating Hearing Loss Matters

Untreated high-frequency hearing loss often leads to social isolation and loss of confidence. While a hearing aid won’t restore perfect natural hearing, it is the next best thing - improving clarity, connection, and quality of life.
