Meanings
- uncountableThe input sound level that creates the same output voltage as the receiving microphone in the absence of any sound, and which represents the lowest point of the microphone's dynamic range.
- uncountableThe noise radiating from a ship, etc. because of its own operation.
Figure 10.5 typifies this latter condition, in which the self-noise generated at the sonar dome of a warship is seen.
2011, John Carlton, Marine Propellers and Propulsion, page 2531 more example
Causes of ship-radiated noise. This is another important factor, as the noise radiated by a ship is received by all sonar systems on board (self-noise) and imposes limits to the performance achievable when it exceeds ambient noise levels.
