Tuning Forks and Tests
The three tuning forks generally used include : 256 Hz, 512 Hz, 1024 Hz. Most common being 512Hz. 512 because It has appropriate decay time, Less overtones and lies in speech frequency. Compressing the prongs with fingers produces around 70 dB sound and hitting against Knee or elbow 90dB. A prediction of air-bone gap can be made if tuning forks of 256, 512 and 1024 Hz are used. • Rinne test equ...
متن کاملAcoustic Analysis of Used Tuning Forks.
OBJECTIVE In this study, we evaluated used aluminum tuning forks (TFs) for fundamental frequencies (FF), overtones, and decay times. MATERIALS AND METHODS In total, 15 used (1 C1, 11 C2, and 3 C3) and 1 unused (C2) TFs were tuned, and the recorded sound data were analyzed using the Praat sound analysis program. RESULTS It was found that FFs of the recorded sounds produced by the used C2-TFs...
متن کاملRinne revisited: steel versus aluminum tuning forks.
OBJECTIVE (1) Determine whether tuning fork material (aluminum vs stainless steel) affects Rinne testing in the clinical assessment of conductive hearing loss (CHL). (2) Determine the relative acoustic and mechanical outputs of 512-Hz tuning forks made of aluminum and stainless steel. STUDY DESIGN Prospective, observational. SETTING Outpatient otology clinic. SUBJECTS AND METHODS Fifty su...
متن کاملPiezoelectric Quartz Tuning Forks for Scanning Probe Microscopy
In this paper the application of piezoelectric quartz tuning forks in dynamic force microscopy is described. For the introduction we give a historical overview and a comparison with traditional cantilevers. In the second section the theories for tuning forks as oscillators for the dynamic force detection are introduced and in the third section the experimental implementation is described. This ...
متن کاملNote: a transimpedance amplifier for remotely located quartz tuning forks.
The cable capacitance in cryogenic and high vacuum applications of quartz tuning forks imposes severe constraints on the bandwidth and noise performance of the measurement. We present a single stage low noise transimpedance amplifier with a bandwidth exceeding 1 MHz and provide an in-depth analysis of the dependence of the amplifier parameters on the cable capacitance.
