I would answer these questions with yet another question. Would any of you discard your audiometers (whatever the vintage) and be limited to the use of tuning forks when faced with a hearing problem? I will concede that you could with understanding, careful testing, and perseverance evaluate your patient's hearing and arrive at a clinically practical deduction with only tuning forks.

Cochlear from retrocochlear involvement, and even in some instances localization of central nervous system lesions.
Accurate records which can be
