Digital technology
Inside your hearing instrument, the microphone,
analog-to-digital converter, digital signal
processor, receiver and other specialized
components process sound that is directed to the
eardrum and auditory system.
The microphone picks up sound waves from
the air and converts them to electrical signals.
The analog-to-digital converter encodes the
electrical signals into a format that is usable
by the digital signal processor.
The digital signal processor has been
programmed by your Audiologist or Hearing Care
Provider to execute the required digital signal
processing for your particular hearing loss.
