A Comparison of Four Hearing Aid Measurement Systems
A Comparison of Four Hearing Aid Measurement Systems is a scholarly work, published in 1977 in ''Journal of speech and hearing research''. The main subjects of the publication include hearing loss, acoustics, physics, Structural health monitoring, overtone, total harmonic distortion, Speech enhancement, THD analyzer, distortion, hearing aid, Amplitude distortion, mathematics, and Nonlinear distortion. Results were equivalent for frequency response and second harmonic distortion, whereas significant differences occurred for total harmonic distortion and third harmonic distortion at both the low and high frequencies.
