In primary care settings, the Rinne would be most effective as part of a screening program for conductive hearing losses, but not as the sole indicator for referral. Sensitivity for all groups was improved by interpreting equivocal results as indicating a conductive loss.ĭespite reports of poor reliability, the 512-Hz Rinne tuning fork test can be an important tool in an otology practice for the detection of conductive hearing losses and for confirming audiometric findings. Sensitivity was lower when masking was not used and lowest when the Rinne was performed by a less-experienced tester. Made of aluminum alloy and designed to meet medical requirements, the different frequencies of the tuning forks test hearing capabilities as well as testing. Results showed the 512-Hz Rinne tuning fork test could be very effective at detecting conductive hearing losses when performed by an experienced tester and when masking was used. Sensitivity of the 512-Hz Rinne tuning fork test was assessed by comparing tuning fork results with the pure-tone average air-bone gap. The effects of tester experience, the use of masking, and the interpretation of equivocal (+/-) Rinne results on test reliability also were examined.ġ,000 adult patients (2,000 ears) seen for their initial otologic evaluation.

We recommend that 512 Hz Rinne test should be used as a screening tool for the detection of conductive hearing loss.This study aimed to examine the reliability of the 512-Hz Rinne tuning fork test to detect conductive hearing losses.

The 512 Hz Rinne test can detect the air-bone gap of 30 dB or greater which indicates the surgical role with the sensitivity more than 90%. Available in 3 Frequencies 128, 256 and 512 Hz. Conclusion: This study demonstrated that the 512 Hz Rinne test had better accuracy than the 256 Hz Rinne test for the diagnosis of conductive hearing loss. The sensitivity was even higher (more than 90%) if the air-bone gap was equal to or greater than 30 dB. The 512 Hz Rinne test had sensitivity over 80% when the air-bone gap was equal to or greater than 20 dB. The specificity and accuracy of the 512 Hz Rinne test was markedly greater than the 256 Hz Rinne test (91.18 % vs. Tuning forks of higher frequency have shorter decay time (how fast the tuning fork loses vibratory energy) and are difficult to activate for them to be heard with a moderate or severe sensorineural impairment. The 256 Hz Rinne test had higher sensitivity than the 512 Hz Rinne test (93.83% and 71.95% respectively). Why tuning fork of 512 Hz is ideal for hearing tests Tuning forks of lower frequency produce more bone vibration.
Results: During the study period, 246 ears with conductive hearing loss and 246 ears with non-conductive hearing loss were recruited.
The audiometry was performed on the same day and the results were compared. Methods: The patients with hearing problems recruited from out-patient unit were tested with the 256 Hz and 512 Hz aluminum quick Rinne test. Objective: To study the sensitivity, specificity and accuracy of the 256 Hz and 512 Hz aluminum tuning fork in the detection of conductive hearing loss by quick Rinne test.
