Acoustic Leakage Tester is our latest tool for H&S departments and audiologists. Leakage testing of the tip or mould when fitted in the ear canal ensures correct fitting, if the leakage is zero then the fit is correct therefore the user is guaranteed to have hearing protection working at the certified level.
DECʼs mass meters are used in mould manufacturing to measure the acoustic mass of the auditory canal. Using DEC design rules for the canal the mass meter is a quantified check that the canal is correct.
