Knowledge about tuning forks, what determines the frequency of tuning forks

The frequency of the tuning fork is determined by the modulus of elasticity of the material.

At present, the tuning fork frequency most commonly used by ** families is 440Hz, which has long been used as the tuning standard for orchestras, and in recent years, the tuning frequency has gradually become more common at 442Hz, because he is also the second string of the violin, also known as the A string.

Introduction The tuning fork was invented in 1711 by the Englishman John Schol, a court trumpeter, composer Georg Friedrich Handel and Henri Purcell, both of whom wrote passages specifically for him to perform, and he was also a lute player The lute is very difficult to tuneSchauer invented a tuning fork to tune the lute to the lute.

The notes produced by the tuning fork when struck are very faint and often only heard clearly when it is brought to the ear, so sometimes the tuning fork is pressed against a solid plane such as a table after the strike, which makes this plane act as a resonant plate and greatly increase the volume.

The sound produced by a tuning fork with a frequency of 512 Hz is higher and the sound produced by a tuning fork with a frequency of 256 Hz is lower in tone, so it can be concluded that the higher the vibration frequency of the emitter, the higher the pitch.

Hit the tuning fork on the right side with a rubber hammer to make a sound, and then press the rubber hammer on the tuning fork to make it stop vibrating, and we will hear the tuning fork on the left side bounce the ball up at the same time as it makes a sound, and this phenomenon is called resonance.

The modulus of elasticity of the material.

At present, it is the most commonly used tuning fork for ** home, with a frequency of 440Hz. This pitch has long been used as the standard for orchestras (in recent years, the frequency of tuning has become more common at 442 Hz), because he is also the second string of the violin (also known as the A string).

The order is as follows: the pitch of the fourth string, the third d, the second string, the first string, the first string, the e) and the first string of the viola (the fourth string, the third string, the second string, the second string, the first string, the a). However, there are also a variety of tuning forks of other pitches on the market, such as tuning forks that produce all the pitches of the piano.

The tuning fork was invented in 1711 by the Englishman John Shore. He was a court trumpeter, and composers Georg Friedrich Handel and Henri Purcell wrote passages in which they were performed for him. He was also a lute player, and the lute was very difficult to tune, so Schauer invented a tuning fork to tune the lute violin.

The notes produced by the tuning fork when struck are so faint that they are often only audible when they are brought to the ear. For this reason, the tuning fork is sometimes pressed against a solid flat surface such as a table after a stroke, which makes this flat surface act as a resonant plate, greatly increasing the volume.

Purpose 1, ** musical instrument.

There are many keyboard instruments with tuning fork-like elements, the most famous of which is the electric piano. In electric pianos there are elements that act like tuning forks and have hammers to make them sound.

2. Electromechanical watch.

The electromechanical watch was developed by Max Ezel for Bulova under the name "Accutron". This watch uses a 360 Hz tuning fork as well as a battery for a fairly high degree of accuracy. In 1977, production of this watch was discontinued.

Explanation of tuning fork

Unaffected by general temperature differences, a metal appliance with two forkheads, which, when struck, produces a fixed tone that is almost unaffected by homophony, and can be used for tuning musical instruments and determining standard pitches Detailed explanation of sound-producing instruments made of steel. Shaped like a fork, it makes a sound when struck with a small mallet. Tuning forks come in different lengths and thicknesses to produce sounds of various pitches, which can be used to adjust the instrument and help the singer set the pitch.

Tuning forks are steel or aluminum alloy sounders in the shape of a "Y", and various tuning forks can vibrate with different frequencies of pure tones due to their different qualities and wishbone lengths and thicknesses. The tuning fork examination is a simple and reliable common diagnostic test to distinguish the nature of deafness, transliterative hearing loss or sensory hearing loss.

Using a tuning fork to take the "standard tone" is one of the most important aspects of the piano tuning process. Its importance lies in the fact that it is related to the pitch position of each key of a piano.

In teaching, a tuning fork can be used to demonstrate resonance.

Tap the tuning fork to collect the sound waveform. The test found that when the tuning fork was tapped, the amplitude of the tuning fork was small, the amplitude of the waveform was small, and the sound produced by the tuning fork was also small. When you hit the tuning fork again, the amplitude of the tuning fork is large, the amplitude of the waveform is large, and the sound made by the tuning fork is also large.

Note: Loudness is related to the amplitude of the tuning fork vibration. The greater the amplitude, the greater the loudness; The lower the amplitude, the less loudness.

Chinese name: tuning fork.

Basic explanation: A steel or aluminum alloy sounder in the shape of a "Y".

Uses: Examination in identifying the nature of deafness.

Pedagogical application: Can be used to demonstrate resonance.
