In order to assess the validity of using various ear tips, tympanometry and acoustic admittance were studied in 20 young healthy subjects, with 3 different types of ear tip used to seal the external auditory canal. Significant variations in the admittance components and tympanometry curves were observed, resulting most probably from changes in the canal volume and the physical nature of the tips. It appears advisable to develop and adopt an appropriate, standard ear tip for studies of admittance audiometry.
