The Physiologic Audiometer

M.A.S.T.E.R II is an essential addition to the clinical electrophysiological test battery, especially when testing patients for whom behavioral audiometry may be unreliable, such as:

• Infants and young children
• Children or adults with special needs
• Workers' compensation cases

M.A.S.T.E.R II program offers:

• Patented technology that obtains frequency-specific auditory threshold information
• Test 8 frequencies at the same time resulting in data collection that is 3 times faster
• View real-time EEG and the response spectrum
• Easy tracking of results. Table on the collection screen records the f-ratio for each frequency collected at each intensity level
• Printing of physiological audiogram with air conduction, bone conduction, and sound field data on the same audiogram
• Test both ears using a Cz to Nape or Cz to Mastoids montage
• Masking is available for bone conduction or unilateral hearing loss.

Why Professionals Choose M.A.S.T.E.R II?

Validation of M.A.S.T.E.R II technology by peer-reviewed research publications
M.A.S.T.E.R was developed in cooperation with Sasha John, Ph.D., Terence Picton, M.D., Ph.D. and additional researchers at the Rotman Research Institute of Baycrest Centre, Toronto, Ontario. The research validating the M.A.S.T.E.R technology, from facilities worldwide, is available at www.mastersystem.ca.

Exponential Modulation
This stimulus option enhances the response amplitude at low (500 Hz) and high (4000 Hz) frequencies so that responses can be obtained closer to threshold.

F-Ratio
The most accurate Auditory Steady State Response (ASSR) method of response detection to assist in predicting behavioral audiometric thresholds even for normal hearing and mild hearing loss.

Weighted Averaging
Improves data collection accuracy and reduces test time.

User Defined Averaging Time
M.A.S.T.E.R allows one to use individual clinical judgment to determine the
averaging time - shorter for severe to profound losses and longer for mild and moderate losses.

Calculation of Noise Floor & Response Amplitude
Monitoring the noise floor and amplitude per ear and per frequency assists you in determining if continued averaging is needed in order to obtain a response, therefore reducing test time and increasing the ability to obtain true thresholds.
