Advanced OTC Hearing Aid Technology & Natural Sound

Natural Sound, Effortless Listening

Hearing Aid Amplification Improves Speech Clarity

NAL-NL2 Based Nonlinear Amplification

Yeasound products uses the NAL-NL2 fitting formula, hearing algorithm widely used by hearing professionals. The nonlinear amplification boosts soft sounds to make speech easier to hear while controlling loud sounds to keep them comfortable. In contrast, basic amplifiers simply increase the volume of all sounds, which might harm user's hearing.

Dual Compression Balances Speech And Background Sound

Dual Compression System

Our Dual Compression System blends fast and slow compression, automatically adapting to environments for clear, natural speech. Fast compression quickly controls loud volume spikes, while slow compression keeps steady sounds like dialogue and background music natural.

Ultra Low Latency

Powered by a high-performance chip, Yeasound delivers just 5.3ms ultra-low latency for near real-time processing. This greatly shortens sound delay, synchronizes speech with lip movements, preserves natural clarity even in complex acoustics, and cuts down echo and perceived lag for a smoother, more comfortable listening experience in noisy environments.

Hear the voice, Not the noise

Hearing Aids Reduce Traffic Noise For Outdoor Listening

Smart Multi-Layer Noise Control

Yeasound analyzes different sound profiles—such as steady background noise, barking, door slams, ringtones, and speech—and processes them in separate layers. Speech and key environmental cues are enhanced, while unwanted noise is attenuated. Sudden sounds are dynamically controlled to ensure safe and comfortable listening.

Directional Hearing Improves Speech In Noisy Places

Directional Beam

Yeasound’s dual microphones create adaptive beams to capture speech from the front while reducing background noise.
Conversations and key environmental sounds are preserved for clear, comfortable listening—even in noisy places like meetings, cafés, or streets.

Hearing Aids Adjust Sound To Changing Environments

Environmental Noise Analysis

Yeasound detects ambient noise in real time and automatically adjusts gain and noise suppression when the environment stabilizes.This ensures optimal clarity and comfort across changing listening scenarios—without user intervention.

Low-level Noise Reduction

Yeasound gently reduces very soft background sounds—like fans, air conditioners, or clocks ticking—while keeping speech and important environmental cues clear. Ideal for users with mild hearing loss or preserved low-frequency hearing, ensuring quiet spaces feel natural and comfortable.

Stream Better, Hear Richer

Unlike traditional hearing aids, Yeasound auto-optimizes Bluetooth sound for richer music and media audio. Boasting a steady 10-meter home connection, it delivers smooth, lag-free sound with no interruptions.

Auracast is a new wireless technology that streams audio directly to hearing aids via Bluetooth LE Audio. It lets you hear public announcements, concerts, and other shared sounds clearly and at your own volume.
