Hearing aids ‘use the same drivers’……
Yes, mechanically the same/similar but:
Different impedance - hearing aid drivers are designed to minimise current use.
Different voltage; operating at 1.2v gives considerable limitations.
Different peak output design - maximising speech around 2.6KHz to emulate canal resonance and also be most effective for speech intelligibility.
Some Audio drivers also use two or more receiver units with different resonant peaks; just like a multi transducer speaker with crossovers.
The same technology underpins a standard Ford truck and my SL; I know which one speeds up and slows down better though.
