What is digital signal processing (DSP) in modern hearing aids and what advantage does it provide over analog processing?
-
A
DSP uses vacuum tubes for amplification; it is louder than analog
-
B
DSP converts sound to binary data for programmable, precise manipulation of frequency-specific gain, noise reduction, and compression; it provides greater flexibility and accuracy than analog
-
C
DSP eliminates the need for microphones in hearing aids
-
D
DSP is only used in cochlear implants, not hearing aids
