The sound's source was roughly triangulated to , a remote point in the South Pacific Ocean west of the southern tip of South AmericaThe sound was detected by the Equatorial Pacific Ocean autonomous hydrophone array, [1] a system of hydrophones primarily used to monitor undersea seismicity, ice noise, and marine mammal population and migration.
Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. [17]
Noise pollution may have caused the death of certain species of whales that beached themselves after being exposed to the loud sound of military sonar. [70] (see also Marine mammals and sonar) Up until recently, most research on noise impacts has been focused on marine mammals, and to a lesser degree, fish.
NOAA's Christopher Fox did not believe its origin was man-made, such as a submarine or bomb. While the audio profile of Bloop does resemble that of a living creature, [ 4 ] the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale .
Psychoacoustic analysis reveals that sound pressure level is a less than ideal predictor of human reception of noise, so efforts have been made since the 1960s [6] [7] to apply loudness metrics instead, which can incorporate other factors such as spectral and temporal auditory masking and level-dependent frequency weighting to more accurately ...
Other audience members disputed the orgasm theory, offering that the woman could have made the noise while waking after having fallen asleep. Some worried that it could have been related to a ...
Noise-cancelling headphones and sound-isolating earphones can help one avoid turning the volume up to overcome loud background noise. Sound measurement apps can help one find out how loud sounds are. If not measuring the sound levels, a good rule of thumb is that sounds are potentially hazardous if it is necessary to speak in a raised voice to ...
Bella, a cat from Huntingdon, Cambridgeshire, broke the Guinness World Record for the loudest purr in October. Measuring 54.6 decibels, the purr was equivalent to the volume of a boiling kettle.
