Masking in Audiometry. £200 per person. Booking form TJ Audiology. Suitable for audiologists or hearing aid dispensers who carry out audiometry routinely in their role. This 1 day training course will review the 3 rules of masking used during pure tone audiometry according to BSA procedures. It will include: Theory of cross hearing and inter-aural attenuation; How and when to employ masking
CONCLUSIONS These results can be used as reference values for masking of pure tone audiometry. But, further studies with large population should be done to get more precise results and contributing factors to IA values.
25/11/2015 · Pure-tone audiograms were available for the affected ear before and after the incident (i. e., a sudden hearing loss). The severity of the hearing loss was 53.75 dB HL and, thus, above the predefined value of 50 dB HL. Grading of hearing impairment (for the affected ear) was 2, which is “moderate impairment”.
Using second-stage audiometry screen may be beneficial as it may provide more accurate results. 20 The current study therefore evaluated the performance of self-reported hearing loss in isolation and in combination with pure tone audiometry screening in PHC clinics in South Africa.
Pure Tone Audiometry Pure Tone Audiometry measures the patient’s peripheral hearing sensitivity, or the softest levels they can hear pure tones at a variety of frequencies.

SHOEBOX Audiometry Pro is a clinical audiometer with the advanced diagnostic capabilities of a traditional audiometer, in one portable, easy-to-use solution
accurate and elaborate tests with pure-tone audiometry masking is also carried out by sound whose intensity is capable of being accurately measured. For this purpose a sound generator is used for the untested ear, and this feeds this ear with a continuous sound of measureable intensity in decibels. Normal threshold for Bone conduction for most frequencies is 45 – 50 db higher than for air
Pure tone audiometry screening should take place in a very quiet room. Perform an environmental noise level check before performing screenings in any environment. Pause the screening if any distracting noise occurs. Perform thresholds only when there are hearing concerns or a child does not pass pure tone audiometry. Thresholds are solely to provide more information for referral. Referrals …

What does an Audiometry Nurse do? Audiometry Nurses provide comprehensive, standardised and professional hearing health services to a variety of age groups. This includes collaboration with newborn hearing screening programs, paediatric screening, health history, otoscopy, tympanometry and pure tone audiometry (including masking) for children and adults, interpretation of assessment results


Masking is the method used to establish the true responses from the test ear. The idea of masking is to raise the threshold of the non-test ear so that we can be sure that the results obtained are correct for the ear being tested. This may be achieved by introducing a masking noise into the non-test ear of the appropriate intensity to prevent it from detecting the test signals. To predict

Pure tone audiometry (PTA) is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss. Thus, providing the basis for diagnosis and management.

31/03/2010 · Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems. Pure-tone thresholds (PTTs) indicate the softest sound audible to an individual at least 50% of the time. Hearing sensitivity is plotted on an audiogram, which is a graph displaying intensity as a function of frequency.

Masking Dilemma. This situation occurs when there is a conductive type hearing loss in both ears, which is moderate to severe. The dilemma is that an adequate intensity to mask the non-test ear crosses over to the testing ear and invalidates the thresholds.
