He is best known for developing hearing tests with tuning forks and his work to improve education for the hearing impaired. He was also the first physician to provide a clear understanding of mastoiditis.
The following medical terms are named after him:
- Bezold's abscess
- Bezold's mastoiditis: mastoiditis with perforation into the gigastric groove that creates a deep neck abscess.
- Bezold's sign: indication of descending mastoiditis
- Bezold's test: method of testing deafness by use of a tuning fork
- Bezold's triad: Three symptomatic indications of otosclerosis: 1. diminished aural perception of low frequency tones, 2. retarded bone conduction, 3. negative Rinne test
- Bezold-Edelmann continuous scale: A series of tuning forks along with Galton's whistle or monochord, in which all perceptible notes can be heard in continuous sequence. Named along with physician Adolf Edelmann (1885-1939}.
