Inspection / analysis of railroad vehicle’s
component parts by hammering sound
Data example of FFT analysis by the
LA-0703 FFT analysis
This example shows how to inspect
component parts of a railroad vehicle by using the
LA-7500 High performance sound level meter. Hammer the
component parts and measure the hammering sound while
checking it through headphones.
By adding the LA-0703 FFT analysis
software (option), you can perform FFT analysis of the
sound at the measurement field.
Recording those required data helps to
evaluate by comparison with the previous data.
The LA-0704 sound recording function
(option) can record the sound to an SD card at WAV
format. It is useful for detailed sound analysis
off-line by using FFT analyzer etc.
