How Is Pitch Measured?

Step, or frequency, is the measure of cycles per unit of time of a sound. It ‘s a physical measurement. It is possible to measure the field with high precision using electronic tools. It is also possible to measure the density around the ear. The field of measurement is important in fields such as music, engineering, music, acoustics, and psicoacústica.

 

Units.

The unit is more commonly used to measure the density is hertz. Hertz is a measure of the cycles per second. Sound waves are oscillating phenomena in the air. A sound wave oscillates between high and low air pressure. A single cycle involves the wave reaching the high pressure, falling to low pressure and reaching high pressure again. However, many times a sound wave does that in a second is the number of cycles per second and, therefore, the number of Hertz.

The oscilloscope

Scientists and engineers often use oscilloscope to measure the field. An oscilloscope is useful to look at the waveform signal during the measurement of your pitch. An oscilloscope creates a graphical representation of a wave form. To use an oscilloscope to measure the density, the user connects the signal to oscilloscope using audio cables or a microphone. The user looks at the display of the oscilloscope and adjusts the buttons until the form of stationary wave. When the stationary wave form, the user reads the settings of the controls, indicating the frequency in Hertz.

The meter

A digital frequency meter is another way of measuring field. A frequency counter calculates the frequency of input and provides a numerical reading in Hertz. The user connects the meter in the same way as is the case with the oscilloscope. When fed with a stable release, the meter will indicate the pitch in Hertz. The advantage of using this method on the oscilloscope is that it provides a more rapid result. The disadvantage is that the wave form is invisible.

Ear

The simplest way but less need for measuring field is doing it by ear using a musical instrument such as a piano. To measure the density, the listener listens to the sound that she wishes to measure, then play the piano keys until she found the key that is more similar to the tone of the sound. The tone of the sound is approximately the same as the name of the note. Or, the user may refer to a chart that gives the frequency of each note
