This example shows how to analyze tire
squeal sound which occurs in sliding velocity of a tire.
Record the squeal sound to an SD memory card in the
LA-7500 High performance sound level meter up to 15 minutes per measurement. By using the
OS-2720 FFT analysis pack, it can play back the recorded
data on a PC with sound function or perform FFT
analysis. We can also provide the OS-2740 sound quality
evaluation pack and the OS-2760 fluctuation sound
analysis pack.
