Rinne test: Does the tuning fork position affect the sound amplitude at the ear?
Background Guidelines and text-book descriptions of the Rinne test advise orienting the tuning fork tines in parallel with the longitudinal axis of the external auditory canal (EAC), presumably to maximise the amplitude of the air conducted sound signal ...

A study of small sized quartz tuning fork using finite element analysis
This is a preliminary study to small sized quartz tuning fork operating at 32.768 kHz for several types of supporting structure. Tine length and tine width can be calculated by Euler-Bernoulli equation (Exact Solution), but the base shall be analyzed by ...

A three million Q factor tuning fork resonator based on a vibration isolation structure
The quality factor (Q factor) is one of the most important parameters for a resonant sensor since it determines the performance of the resonant system. The mass distribution imbalance caused by the fabrication error has a great impact on the anchor loss,

On the nonlinearity of a tuning fork [PDF]
Tuning fork experiments at the undergraduate level usually only demonstrate a tuning fork's linear resonance. In this paper, we introduce an experiment that can be used to measure the nonlinear tuning curve of a regular tuning fork.

The Analysis of the Tuning Fork [PDF]
WITH reference to the letter of Mr. Stanley in NATURE, vol. xxvi. p. 243, I notice the following sentence:—“If we may apply this principle to stringed instruments, we must look rather to the bridge than the transverse motion of the string, as the communicator of the sonorous vibrations which produces the note.” I thought that this was an admitted fact.
