WebThe Best Depth for a submarine to avoid detection by a hull-mounted sonar is conventionally regarded as the Sonic Layer Depth plus 100 meters. This assumption is based on the premise that maximum downward refraction of sonic energy will occur at the depth of the strongest minimum sound speed gradient, thus causing short horizontal sonar ranges. WebIn a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors. In a 2 detector … WebIn the most basic wireline sonic measurement, an acoustic transducer emits a sonic signal, of between about 10 and 30 kHz, ...
