METHOD AND SYSTEM FOR MEASURING TOTAL SOUND PRESSURE LEVEL OF NOISE, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

A method and system for measuring the total sound pressure level of noise, and a computer-readable storage medium, wherein same relate to the field of acoustics. The method for measuring the total sound pressure level of noise comprises the steps of: acquiring a time domain digital signal of a sound pressure signal of noise (S101); according to the time domain digital signal of the sound pressure signal, acquiring a frequency domain signal of the sound pressure signal (S102); according to the frequency domain signal and based on Parseval's theorem, acquiring a sound pressure effective value of the sound pressure signal (S103); and converting the sound pressure effective value into the total sound pressure level of the noise (S104). The method for measuring the total sound pressure level of noise has the advantage of a fast measurement speed.
