Sound Creation and Manipulation UNIT 35 LO1
A coustic Theory & Fundam ental Sounds The air that is produced from vibrations from a source is sound. Sound waves are many different waves projecting different frequencies together. Each of these are called a sine wave but together are called harmonics. Amplitude, frequency and wavelength produce different waveforms. The distance between the highest point in one wave and the highest point in another wave is called wavelength. Wavelengths affect frequency either by being short (high frequency) or long (low frequency). Frequency is just the speed of the vibration, the speed of the vibrations will then affect pitch to the human ear, this is measured in ‘cycles’ by the number of waves produced each second. The fundamental frequency is the lowest frequency able to be produced by the instrument being used, so as the harmonics are multiples of the fundamental frequency, the frequency will increase in multiples of hertz (Hz). Within my own project, I used the ...
