Webbor 10,000 Hz; calculating broadband noise over a bandwidth that includes frequencies up to 25,000 Hz can hide noise problems at the important frequencies that are actually being analyzed. Some accelerometer designs have a very high noise at frequencies below 100 Hz, and have very low noise at 20,000 to 25,000 Hz. In science, Brownian noise, also known as Brown noise or red noise, is the type of signal noise produced by Brownian motion, hence its alternative name of random walk noise.

Webb7 apr. 2024 · High-pitched noise is typically associated with ultrasound, which is sound at a frequency too high for humans to hear. Moreover, any sound that crosses the level of 5000hz and reaches above 20000hz is counted as high-pitch noise. This type of noise is typically unpleasant to listen to and can cause discomfort or even pain in some people.
