Speech Interference Level (SIL) is an acoustical parameter calculated from sound pressure levels measured in octave bands.It is used to characterize a noise signal in the frequency range where the human ear has its highest sensitivity.
In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized.
A standing wave. The red dots are the wave nodes. A node is a point along a standing wave where the wave has minimum amplitude.For instance, in a vibrating guitar string, the ends of the string are nodes.
Google Docs is an online word processor and part of the free, web-based Google Docs Editors suite offered by Google. Google Docs is accessible via a web browser as a web-based application and is also available as a mobile app on Android and iOS and as a desktop application on Google's ChromeOS .
Electromagnetic interference divides into several categories according to the source and signal characteristics. The origin of interference, often called "noise" in this context, can be man-made (artificial) or natural. Continuous, or continuous wave (CW), interference comprises a given range of frequencies.
