Description

A range of researchers have looked to address this question, with resonant frequencies of the human middle ear often reported informally as typically falling between 800 and 1200 Hz (Shanks, 1984). More specific estimations are available, such as Valvik et al. (1994). These authors reported a mean resonant frequency of 1049 Hz (SD = 261) based on 100 non pathological ears. More recently, Polat et al (2015) described normative data from 110 normally hearing individuals from the Turkish population using Wideband Tympanometry (WBT). The mean resonant frequency reported in this study was 965 Hz (SD = 234).

Michael Maslin
After working for several years as an audiologist in the UK, Michael completed his Ph.D. in 2010 at The University of Manchester. The topic was plasticity of the human binaural auditory system. He then completed a 3-year post-doctoral research program that built directly on the underpinning work carried out during his Ph.D. In 2015, Michael joined the Interacoustics Academy, offering training and education in audiological and vestibular diagnostics worldwide. Michael now works for the University of Canterbury in Christchurch, New Zealand, exploring his research interests which include electrophysiological measurement of the central auditory system, and the development of clinical protocols and clinical techniques applied in areas such as paediatric audiology and vestibular assessment and management.
