2. Tuning fork - Wikipedia

   en.wikipedia.org/wiki/Tuning_fork

   Tuning fork pitch varies slightly with temperature, due mainly to a slight decrease in the modulus of elasticity of steel with increasing temperature. A change in frequency of 48 parts per million per °F (86 ppm per °C) is typical for a steel tuning fork. The frequency decreases (becomes flat) with increasing temperature. [6]

4. Sympathetic resonance - Wikipedia

   en.wikipedia.org/wiki/Sympathetic_resonance

   Sympathetic resonance has been applied to musical instruments from many cultures and time periods, and to string instruments in particular. In instruments with undamped strings (e.g. harps, guitars and kotos), strings will resonate at their fundamental or overtone frequencies when other nearby strings are sounded.

5. Piano key frequencies - Wikipedia

   en.wikipedia.org/wiki/Piano_key_frequencies

   For other tuning schemes, refer to musical tuning. This list of frequencies is for a theoretically ideal piano. On an actual piano, the ratio between semitones is slightly larger, especially at the high and low ends, where string stiffness causes inharmonicity, i.e., the tendency for the harmonic makeup of each note to run sharp.

6. Beat (acoustics) - Wikipedia

   en.wikipedia.org/wiki/Beat_(acoustics)

   Diagram of beat frequency. In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones

7. John Shore (trumpeter) - Wikipedia

   en.wikipedia.org/wiki/John_Shore_(trumpeter)

   Over time, tuning forks were adapted for use in medical and therapeutic settings, where their precise frequencies have been harnessed for healing and therapeutic purposes. [ 3 ] Tuning forks are known for their nearly pure frequency response, emitting a clear, unwavering tone that is free from the complex overtones found in other instruments.

8. Weber test - Wikipedia

   en.wikipedia.org/wiki/Weber_test

   The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]

9. Melde's experiment - Wikipedia

   en.wikipedia.org/wiki/Melde's_experiment

   Melde's experiment is a scientific experiment carried out in 1859 by the German physicist Franz Melde on the standing waves produced in a tense cable originally set oscillating by a tuning fork, later improved with connection to an electric vibrator.
