The microphones cannot make unwanted sound disappear completely. Instead, directional processing and other digital algorithms can alter the relative prominence of sounds.

The Important Directionality Trade-Off

A narrower directional focus can improve attention toward a speaker in front of us, but it may reduce awareness of sounds arriving from the sides or behind.

That distinction matters.

A focused setting may be useful during a face-to-face restaurant conversation, but it may be inappropriate when walking outdoors, crossing a road or moving through an unfamiliar environment where awareness of surrounding sounds is important.

We should therefore treat directional focus as a situational listening adjustment, rather than a setting that should remain permanently activated.

4. Adjust Noise Reduction for Loud Environments

Background-noise management is another important component of comfortable hearing.

Busy environments contain many competing sounds: dishes, cutlery, ventilation systems, traffic, machinery, multiple conversations and intermittent impact noises. Hearing aids use digital processing to distinguish and manage different acoustic signals.

When noise becomes distracting, an appropriate noise-reduction adjustment may make listening more comfortable.

However, maximum noise reduction is not necessarily desirable in every environment.

Loud Environment vs Quiet Environment

In a genuinely noisy location, stronger noise management can help reduce listening fatigue and make the acoustic scene more manageable.

In a quiet environment, excessive processing may make certain low-level environmental sounds feel less prominent than expected.

For example, we may want to remain aware of:

• A kettle boiling
• A person approaching from another room
• A door opening
• Quiet household conversation
• Birds or outdoor sounds
• Soft environmental cues

Consequently, the ideal setting depends on what we are trying to hear at that moment.

5. Use Signia Assistant When Manual Adjustments Are Not Enough

When the standard controls do not adequately address a listening problem, Signia Assistant can provide another level of personalisation on compatible Signia hearing systems.

Rather than experimenting randomly with multiple controls, we can describe the listening difficulty in straightforward terms.

For example:

• “Speech is unclear.”
• “The background noise is too loud.”
• “Voices sound too sharp.”
• “The room sounds overwhelming.”
• “I can hear people but cannot understand their words.”
• “The sound feels uncomfortable.”

The system can then suggest an adjustment based on the reported listening situation.

This can be useful because hearing-aid adjustments are often highly individual. Two people with similar hearing-test results may have different preferences for loudness, clarity, noise management and sound quality.

Make Small, Meaningful Adjustments

When using an app-based adjustment system, we should listen carefully after each change.

Instead of repeatedly changing several settings at once, it is usually easier to determine what works when we make one adjustment, listen for a short period and then decide whether another change is necessary.

This creates a clearer relationship between the adjustment and the resulting listening experience.

6. Remember That Signia Assistant Requires Connectivity

Signia Assistant is designed as a connected, cloud-based feature, so access can depend on an internet connection and compatible devices and software.

This means we should not assume that every app function will remain available when the phone is completely offline.

Before travelling, particularly by air, it is sensible to become familiar with the hearing-aid programmes and controls that can be used directly through the hearing aids and app without relying on an online assistant.

The exact functionality available can depend on the hearing-aid model, app version, smartphone and individual configuration.

7. Do Not Keep Making the Same Large Adjustment Every Day

One of the most important signs that an app adjustment may not be the real solution is repeated dependence on the same substantial change.

If we consistently find ourselves:

• Increasing volume significantly
• Increasing noise reduction every day
• Repeatedly changing speech enhancement
• Constantly correcting sharpness
• Frequently switching between the same settings
• Struggling in the same listening environments

then the issue may require professional attention.

An app can provide useful personal adjustments, but it should not replace a proper hearing-aid fitting when the underlying settings are consistently unsuitable.

Our hearing needs can also change over time. Changes in hearing thresholds, listening habits, ear health, hearing-aid technology or the acoustic environments in which we spend most of our time can all affect the fitting experience.

How to Use the Signia App in a Restaurant

Restaurants are among the most demanding environments for hearing-aid users because several people may be speaking simultaneously while background noise comes from many directions.

A practical sequence is:

Step 1: Select the Appropriate Programme

Start with the listening programme configured for speech or noisy environments rather than immediately increasing volume.

Step 2: Position Ourselves Strategically

Whenever possible, sit where the primary speaker is relatively close and directly in front of us. Good positioning can complement the hearing aids’ directional processing.

Step 3: Use Speech-Focused Controls

If speech remains difficult to understand, use an available speech-enhancement feature such as Speech Boost when supported by the hearing-aid system.

Step 4: Increase Noise Management if Necessary

If surrounding noise remains intrusive, make a moderate noise-reduction adjustment.

Step 5: Reassess Before Making Another Change

Listen for several moments. If the sound becomes muffled, unnatural or excessively processed, reverse the last adjustment rather than continuing to increase processing.

Using Signia Hearing Aids in Meetings

Meetings can present a different challenge from restaurants because the speaker may change frequently.

A very narrow directional setting may be helpful when one person is presenting from directly ahead. However, it may become less suitable when several participants are speaking from different locations.

For meetings, we should consider:

• Where the primary speakers are sitting
• Whether the room has an amplification or microphone system
• How much background noise is present
• Whether we need awareness of people speaking from the sides
• Whether automatic environmental processing is performing adequately

If difficulty occurs consistently in professional meetings, an audiologist can evaluate the hearing-aid fitting and discuss additional options for challenging listening environments.

Signia App Volume Control vs Programme Selection

These two controls should not be treated as interchangeable.

The most effective sequence is generally to select the appropriate listening mode first and fine-tune individual controls afterwards.

Why Speech Can Remain Difficult Even When Sounds Are Loud Enough

Hearing loss does not affect every frequency equally. Many people experience greater difficulty hearing certain speech frequencies, particularly those important for distinguishing consonants.

As a result, increasing overall loudness does not necessarily restore speech clarity.

For example, if speech is already sufficiently loud but competing environmental sounds are also amplified, increasing volume may actually make the listening environment more tiring.

Modern hearing aids therefore rely on more than amplification. Digital processing can incorporate directional microphone technology, noise management and speech-oriented processing to make complex acoustic environments more manageable.

This is why selecting the right programme can be more effective than repeatedly turning the volume upward.

When the Signia App Is Not the Solution

App adjustments are useful for day-to-day personalisation, but certain problems require professional assessment.

We should arrange a hearing-aid review if:

• Speech remains unclear in most environments.
• One hearing aid sounds substantially different from the other.
• The hearing aids frequently produce feedback.
• Sounds consistently seem too sharp or distorted.
• Noise reduction makes speech sound unnatural.
• We need major volume changes every day.
• The hearing aids no longer seem appropriate for our hearing needs.
• Hearing appears to have changed since the last hearing test.
• A previously comfortable fitting has suddenly become uncomfortable.

An audiologist can check the hearing thresholds, inspect the devices, review programming parameters and determine whether the fitting remains appropriate.
