Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans). [1] This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they ...
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Noise is a term often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a wanted signal. However, in sound perception it can often be used to identify the source of a sound and is an important component of timbre perception (see below).
Background noise is an important concept in setting noise levels. Background noises include environmental noises such as water waves , traffic noise , alarms , extraneous speech , bioacoustic noise from animals, and electrical noise from devices such as refrigerators , air conditioning , power supplies , and motors .
Banging sounds coming from the Titan search zone briefly raised hopes, before the rising submersible was confirmed to have been destroyed in a ‘catastrophic implosion’. What was the banging ...
NASA scientists believe the ominous noises could potentially be the "background noise" of the Earth otherwise known as "Ambient Earth Noise." Since this still lacks scientific confirmation ...
A spectrogram of the soundscape of Mount Rainier National Park in the United States. Highlighted areas show marmot, bird, insect and aircraft noises. Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial.
