Simplified Measurement Scheme for Peak-to-Peak Equivalent Sound Pressure Level of Short-Duration Signals
Short-duration signals are an important acoustic stimulus used in the process of hearing diagnosis,and their intensity needs to be precisely quantified. Addressing the complexity and cumbersome nature of existing measurement schemes for the peak-to-peak equivalent sound pressure level of short-duration signals,two simplified measurement schemes have been designed and validated. The first scheme utilizes an oscilloscope to directly measure the voltage peak-to-peak value of the short-duration signal and calculates the result using known parameters and formula. The second scheme utilizes a sound signal analyzer to read the maximum and minimum sound pressure values of the short-duration signal and then directly calculates the result based on those values. The verification results show that the two simplified schemes can effectively reduce the difficulty of short-duration signal peak-to-peak equivalent sound pressure level measurement,while maintaining the same measurement accuracy as the traditional scheme.
