Directional Microphones in Hearing Aids: Cut Through the Noise

Directional Microphones: smart hearing in busy environments

If you're an active person who struggles to hear conversations in busy spots—like a café in an inner city laneway or a busy sports stadium—you need a practical solution that just works. That solution often comes down to the clever technology inside your device: directional microphones.

At Amplifon, we understand that hearing well isn’t just about making sounds louder; it’s about clarity and connection. That's why the sophisticated design of directional microphones is one of the most important features in our advanced hearing aids. They are designed to give you back control in the noisiest environments, providing the effective, fast solution you are seeking.

What are directional microphones in hearing aids?

Directional microphones in hearing aids are specialised systems designed to focus on sounds coming from in front of you (like a speaker) while actively reducing distracting background noise. This crucial technology uses two or more microphones to create a listening 'beam,' drastically improving speech clarity in challenging listening environments, which is exactly the practical solution you need.

This technology is the core element that allows modern devices to move beyond simply amplifying sound, transforming them into smart, adaptive tools for real-life communication.

How are modern hearing aid microphones different?

Older or cheaper hearing aids often use an omnidirectional microphone setup. This means they pick up sound equally from every direction—in front, behind, and to the sides. While this is fine for quiet environments, it makes hearing a single person in a crowded room nearly impossible.

Modern Amplifon hearing aids primarily use sophisticated directional setups because you need clarity most when life gets loud and complex.

We're here to be your guide, making the most advanced hearing aid technology simple, and suited to your personal needs. Our purpose is to combine superior expertise with ongoing care, so you can step into each day with confidence and joy.

How do adaptive directional microphones work?

The best hearing aids today don’t just have directional microphones; they have adaptive ones which use precise, data-driven performance.

Here is the simple breakdown of how this smart technology delivers clear speech:

Sound capture

The hearing aid has at least two directional microphones spaced slightly apart.

Signal comparison

These microphones capture the exact same sound at slightly different times, depending on the sound's source direction.

Intelligent processing

The hearing aid’s digital processor instantly compares these sound signals. It identifies the target sound (usually speech coming from in front) and the unwanted noise (chatter from the side, traffic from the back).

Noise suppression

The processor then applies noise reduction algorithms to the unwanted background sounds, effectively "cancelling" them out or turning them down.

Focus beam

What you hear is the targeted speech signal, amplified and clear, while the noise is minimised. This is known as the adaptive directional microphone hearing aid feature, because the 'focus beam' changes dynamically as your environment changes.

This adaptive technology is a major leap forward from older dynamic microphone systems, ensuring a consistent, clear experience whether you are in a quiet room or at a busy function in.

Can directional microphones help me hear better?

Absolutely. The primary reason people struggle with hearing loss is not the inability to hear sound, but the inability to understand speech when there is competing noise.


Directional microphones are specifically engineered to solve this problem. They enhance the signal-to-noise ratio, which is the technical measure of how much louder the voice you want to hear is, compared to the background distractions.

Imagine you are trying to enjoy a family BBQ or a lively weekend market. Without directional mics, your hearing aid would amplify the sizzle of the sausages, the drone of the air conditioner, and grandchild’s laughter all at once. With advanced directional microphones, your hearing aids focus on the conversation right in front of you, making that crucial voice stand out clearly against the din.


This feature is particularly valuable for:

  • Restaurants and Cafés: Enjoying a catch-up without the frustration of missing key words.
  • Group Meetings: Focusing on the presenter or speaker without distraction.
  • Public Transport: Understanding announcements or a friend's comment over the rumble of a train.

Frequently Asked Questions about directinoal microphones

Are directional microphones available on invisible hearing aids?

Yes, absolutely. Technological advancements mean that even the most discreet, smallest devices—including invisible-in-the-canal models—now feature multiple, high-performing directional microphone ports. We specialise in connecting you with the latest invisible & mini HAs that offer premium clarity without compromising on size or aesthetics.

Does using a directional mic drain the battery faster?

The digital signal processing required for adaptive directional microphone functionality does use some power. However, modern hearing aids, especially the latest rechargeable hearing aids and batteries, are designed to easily power this crucial technology for a full day of wear. The enhanced clarity and quality of life benefit far outweighs any minimal difference in power consumption.

Can I turn the directional microphone feature off?

In most advanced models, the adaptive directional microphone feature is automatically managed by the hearing aid's processor. It will switch seamlessly between omnidirectional (for quiet, one-to-one settings) and directional modes (for noisy environments). You can always discuss your preferences with your certified Amplifon audiologists who can fine-tune the settings for your specific needs.
