Most audio measurements are made with an instrument which is basically an ac voltmeter. Filters are usually incorporated into the voltmeter for many of the required measurements. Some advanced audio measurements are made with spectrum analyzers, which today are likely to be FFT (Fast Fourier Trans-

This website is a clearinghouse for audio measurement related information with an emphasis on live audio measurements. The goal is to provide useful information regarding how to measure, verify and optimize a sound system, test audio gear to verify proper functionality and to explain the principles of sound system design and optimization as I learn them myself.

By using many audio samples, we are able to gain in the order of 32 db or so in noise reduction (called "FFT gain"). This allows us to dig deep to as low as -150 db looking for distortion products. This floor is well in excess of hearing dynamic range (around -116 dB). Unfortunately this FFT gain is source of a lot of confusion.

In audio test, there are a small number of performance benchmarks that are most important when evaluating a device-under-test (DUT). We call them “The Big Six” measurements. These are: • Level • Frequency Response • Total Harmonic Distortion plus Noise (THD+N) • Phase • Crosstalk • Signal‑to‑Noise Ratio (SNR)

To measure vibrations we utilized a Measurement Specialties ACH-01 piezoelectric accelerometer sensor. The sensor was attached to the enclosure using double sided tape. An amplifier with an integrated analog signal processor was used to amplify the analog output of the ACH-01 sensor.
