Why Hearing Aid Settings Matter for Music

Traditionally, hearing aids and their fitting prescriptions have been designed to maximise speech understanding, even in noisy environments. But many of the features that improve speech clarity can actually degrade music quality.

For decades, people with hearing loss were told hearing aids could not help them enjoy music. This is simply not true. With the right settings and adjustments, hearing aids can deliver a much richer, more natural music experience.

At Harmony Hearing, our specialists are also musicians. We understand the importance of music in everyday life and fine-tune hearing aids to enhance the full listening experience — not just speech.

Why Traditional Hearing Aid Settings Can Harm Music Quality

Speech-Optimised Formulas

Hearing aid manufacturers design their proprietary fitting formulas to maximise speech understanding. For example, Oticon’s Voice Aligned Compression (VAC) emphasises the mid-frequencies (1–4 kHz) where most speech clarity lies.

This works brilliantly for conversations but causes problems for music:

• Music requires balanced amplification across low, mid, and high frequencies.
• Too much mid-frequency boost makes music sound thin, harsh, or unnatural.

Compression Effects

Hearing aids compress sound to fit a wide environment into a reduced hearing range:

• More gain for soft sounds (keeps consonants audible).
• Less gain for loud sounds (prevents discomfort).
• Maximum Power Output (MPO) limits sudden peaks.

Speech needs heavy compression, but music requires a wider dynamic range to preserve the natural contrast between quiet and loud passages. Over-compression makes music sound flat and “squeezed.”

Adaptive Features

Modern hearing aids use features such as directionality, noise reduction, and feedback cancellation to prioritise speech. Unfortunately, these can:

• Mistake sustained musical notes for “noise” and suppress them.
• Treat pure tones or harmonics as feedback and distort them.
• Flatten the richness of live music.

The Widex Allure 330 and 440 have varying levels of advanced sound processing designed around delivering a natural listening experience for music.

Why Music Needs Different Hearing Aid Settings

Frequency Shaping

• Speech formulas boost the mid-frequencies.
• Music preservation requires balanced amplification across lows, mids, and highs to reproduce full tonal richness.

Microphone Mode: Omnidirectional

Switching microphones to omnidirectional mode can be very beneficial. It captures sound from all directions, preserving natural ambience and space.

Example: At a live concert, omnidirectional microphones let you hear not only the instruments but also the hall’s reverberation, giving you a fuller, more immersive experience.

Bandwidth Considerations

• Speech requires amplification up to ~6–8 kHz.
• Music extends far beyond 10 kHz (cymbals, violins, flutes).
• Hearing aids with wider bandwidth (up to 12.5 kHz) preserve these upper harmonics for a high-fidelity experience.

Hearing Aid Settings That Enhance Music Quality

A dedicated Music Program should be installed and customised. Adjustments include:

• Deactivate Frequency Compression/Transposition: Prevents distortion of high-frequency harmonics.
• Widen Input Dynamic Range (80–105 dB SPL): Preserves musical peaks without distortion.
• Reduce Compression: More linear amplification maintains natural contrast.
• Increase MPO: Prevents bass or percussion from sounding distorted.
• Fine-tune Frequency Response: Boost low-frequency warmth and smooth treble for clarity.
• Disable Noise Reduction/Feedback Suppression (for music mode): Avoids clipping sustained notes.
• Adjust Attack/Release Times: Slower settings keep rhythm natural.
• Enable Wideband Frequency Response: Extends treble reproduction.
• Use Direct Inputs (telecoil, line-in, Bluetooth streaming): Ensures the cleanest digital signal.

Avoiding Upward Spread of Masking

Upward spread of masking happens when too much bass covers up delicate treble tones, making music muddy.

Problems caused:

• Loss of detail — harmonics and timbre are lost.
• Reduced clarity — instruments blend together.
• Distorted tonal balance — music sounds boomy.
• Listening fatigue — the brain strains to pick out details.

By carefully balancing bass and treble in the music program, audiologists can keep music clear, detailed, and enjoyable.

Acoustic Coupling and Music Quality

The way hearing aids are fitted in your ears (acoustic coupling) greatly affects music.

If the fit is too open:

• Bass leaks out → music sounds thin.

If the fit is too closed:

• Your own voice sounds boomy (occlusion effect).
• Music can feel blocked or unnatural.

To improve fit:

• Select the right ear tips or earmoulds with correct vent sizes.
• Use a slightly more closed fit to boost bass and richness.
• Consider custom earmoulds with optimised venting for the best music quality.

With the right coupling, music becomes clearer, fuller, and more lifelike.

High-Fidelity Receivers

Oticon’s new miniFit Detect speakers are an example of improving receiver consistency. They have a gain variation of only ±1 dB between units, compared with ±3 dB industry standard. This tighter tolerance ensures balanced stereo soundacross both ears, which is vital for music.

Live Performance Adjustments

At Harmony Hearing, we encourage musicians to bring their instruments into the clinic. This allows us to:

• Fine-tune settings live while they play.
• Use high-fidelity surround sound systems to test across genres.
• Ensure their hearing aids deliver authentic, natural sound for practice and performance.

Takeaway

Hearing aids aren’t just for speech. With the right settings, programs, and acoustic adjustments, they can deliver a rich, dynamic, and enjoyable music experience.

At Harmony Hearing, our Audiologists fine-tune fittings with a passion for music — so you can enjoy every note the way it was meant to be heard.
