Acoustic Noise Spectra (Caltech)

Document #:

LIGO-E2300282-v1

Document type:

E - Engineering documents

Abstract:

Acoustic Noise was measured at different areas on the Caltech campus using a microphone (UMIK1) and an open source software (REW) and plotted on the dBA and NC scales. The measurements, directions and code to process the data are attached.
