When a listener misses out on the quieter and louder moments, and other subtleties woven throughout music, it can compromise their listening experience. A musical passage needs to be input to a hearing instrument with precision in order to be output without compromise.
Most hearing instruments use a 16-bit analog-to-digital (ADC) convertor, which limits the dynamic range of music. A limited dynamic range can lead to both a noisy input and loud notes being distorted. Hearing instruments driven by the Tempus platform, such as Moxi All, offer technology to overcome these issues:
• 24-bit ADC provides sufficient dynamic range to reproduce the highest
level input peaks of music that hearing instrument microphones can
capture without distortion. It also keeps the noise floor extremely low
so even the pianissimo (very soft music) sounds beautiful.
• 119 dB SPL peak input with 101 dB input dynamic range captures a
full range of sound, from quiet to loud, while 11 kHz bandwidth
captures both the low and high frequency inputs to achieve a clean
reproduction of sound.
