Reliability and performance of the acoustic reflectometer.
Test-retest reliability and performance of an acoustic reflectometer were evaluated for 78 patients in two clinical settings. For a majority of the cases, the repeat measurements did not vary by more than one or two units from the first measurement. The accuracy of the instrument, when compared with standard clinical instruments, indicated that the acoustic reflectometer performed adequately with cases of middle ear effusion and could be used most effectively as a supplement to pneumatic otoscopy.
