Final answer:
Acoustic parameters include frequency, pressure, period, and indirectly, amplitude and distance, which play roles in various sound phenomena. Density affects sound properties but is not a direct acoustic parameter.
Step-by-step explanation:
The acoustic parameters that are considered in the context of sound waves include frequency, which is the number of wave cycles that pass a point in one second, expressed in hertz (Hz). Pressure is the force exuded by the sound wave per unit area. The period is the time taken for one complete cycle of the wave to pass a point, usually measured in seconds.
The amplitude of a sound wave, representing the maximum displacement from the rest position, is also a crucial parameter, as it corresponds to the loudness or intensity level, often measured in decibels (dB). The distance between the two points in a medium or between the source and observer can affect how sound is perceived, especially in the occurrence of phenomena like standing waves or a sonic boom.
Density of the medium through which the sound travels can impact the sound's properties, such as its speed, but it's not typically referred to directly as an acoustic parameter.
