äänensignaali
Äänisignaali refers to a signal that represents sound. It is a physical quantity that varies over time and can be interpreted as sound. This variation can be in pressure, particle displacement, or particle velocity. In its most common form, an äänensignaali is a pressure wave propagating through a medium such as air or water.
Äänisignaalit are generated by sound sources, like the human voice, musical instruments, or machinery. These vibrations
The characteristics of an äänensignaali are described by several parameters. Amplitude relates to the loudness or
In digital systems, äänisignaalit are represented as discrete values obtained through sampling and quantization. This process
