Audio amplifiers shut out the noise for earbuds

Augmented hearing companions are audio amplifiers designed to provide noise cancellation for loose- and closed-fit earbuds.

These audio amplifiers implement automatic leakage compensation algorithms and automatic ambient preset selection algorithms.

The AS3460 hearing companions offer low latency of 4.3µs and consume ultra-low-power of 5mW at 1.35V digital core for hybrid ANC.

These devices offer high filter design flexibility with a flexible design tool and filter prediction algorithm.

They provide up to 40dB of noise attenuation over a broad range of audible frequencies providing a quiet acoustic background in almost any environment.

Typical applications for the AS3460 augmented hearing companions include true wireless earbuds, neckband earbuds, on-ear headphones, over-ear headphones, over-the-counter hearing aids, and sleep buds.
