WebTectonic, non-volcanic tremor is a weak vibration of ground, which cannot be felt by humans but can be detected by sensitive seismometers. It is defined empirically as a low-amplitude, extended duration seismic signal associated with the deep portion (∼20–40 km depth) of some major faults. Web17 de jan. de 2024 · Low-Frequency Sound Waves Low-frequency sound waves reside at and below 300 Hz. We perceive these sound waves to have the lowest pitch. Low-end noise comes with a longer wavelength, making it some of the most resilient. Low frequencies travel great distances and pass through walls more than others.
