Calculates the distance-dependent attenuation of sound pressure levels for both point and line sound sources.
Given a distance from the speaker to the receiving point ranging from 1 m to the maximum distance (m),
this calculator computes the sound pressure level at the receiving point at intervals of 1 m up to the maximum distance.
