threshold_detection function - RDocumentation
https://www.rdocumentation.org/packages/bioacoustics/versions/0.2.7/topics/threshold_detection
A threshold value of 14 dB above SNR is recommended. Higher values increase the risk of leaving audio events undetected (false negative). In a noisy recording (low SNR) this sensitivity threshold may be set at 12 dB, but a value below 10 dB is not recommended. Default setting is 14 dB above SNR. channel character.
Audio Detection - ICRealtime

Audio detection picks up abnormalities in ambient sound to trigger an event. The camera determines the range of sound based on the sensitivity and threshold which can be customized. Audio detection is more niche compared to the previous IVS types and would be used in areas where the ambient sound doesn’t change frequently.

Detection Threshold for Sonar - Discovery of Sound in the Sea
https://dosits.org/science/advanced-topics/detection-threshold-for-sonar/
Detection Threshold for Sonar Sonar ( SO und N aviation A nd R anging) is a technology that uses acoustical waves to detect and locate objects in the ocean. Active sonar systems, such as fish finders, echosounders, side-scan sonars, and military sonars, transmit a pulse of sound and then listen for echoes.

To correctly set the THRESHOLD level, place the detector's MODE switch in the threshold-dependent ALL-METAL position. While holding the detector a few feet above ground and away from any metal object, slowly turn the THRESHOLD control until you hear a very slight audio tone through the speaker or headphones.
