How It Works

Able Planet embeds patented LINX AUDIO® into audio and communication devices to enhance sound quality and speech clarity For All Levels of Hearing™. Here’s how it works:

Sound quality and speech intelligibility are impacted by high frequency sounds

Hearing loss associated with age usually begins in the higher frequencies, or the “High Tones.” If you lose the ability to clearly hear these tones, high pitched sounds like “f”, “s” and “th” will be difficult to discriminate, and music may not sound as lively.

Chart A - Red boxes in chars A & B highlight identical frequency ranges.

LINX AUDIO® creates high frequency harmonics that enhance sound quality and speech clarity of difficult to hear words or notes, and increase the perception of loudness without increasing volume. LINX AUDIO® provides full rich sound and enhanced speech clarity even at lower volumes, which may lead people to “Turn it Down™” to preserve hearing. An analogy of a richer sound might be the difference you hear when you play a “C” note on a piano, as opposed to a “C” Chord. The “C” Chord demonstrates the impact of adding harmonics to the audio signal.

LINX AUDIO® filters undesirable sound

LINX AUDIO® removes undesirable sounds and noise making it easier to hear high frequency words or notes where clarity is often lost, maximizing full rich sound for music, and enhancing clear voice for speech intelligibility.


LINX AUDIO® reduces distortion

Increasing volume increases all sounds, including distortion. As volume is increased, standard audio products hard clip peaks with traditional square-edge characteristics (red). LINX AUDIO® reduces harsh sounds by soft-clipping distortion (yellow).
