Mysticetes (Baleen Whales)īaleen whales generally make low-frequency (0-5kHz) sounds. The loudness of a sound can be seen by the color scale of the sound in the spectrogram, with lighter colors implying louder sounds. Time here is measured in minutes and seconds, in the format mm:ss.
Time is shown along the bottom of the graph (the x-axis). Frequency is most often measured in hertz (Hz) or kilohertz (kHz). The frequency of the sound is labeled on the vertical or y-axis. Sounds in the Ocean: Fish and InvertebratesĪ spectrogram is a visual way to display sound. Sounds in the Ocean: Environmental and Anthropogenic.Some sounds (in particular from mysticetes/baleen whales) are very low frequency, and you may need high-quality speakers to hear the recording.

Scientists in the Northeast's Passive Acoustic Research Group and their colleagues have compiled these sounds to provide examples of the variety and breadth of animal sounds. Passive Acoustic recorders can be towed behind a ship, mounted on mobile ocean-going robots, or placed at specific underwater sites and left out for days, months, or even years, capturing that location’s soundscape until the recorder is retrieved. Changes in the rate, pitch, and/or structure of sounds communicate different messages.
Sounds are particularly useful for communication because they can be used to convey a great deal of information quickly and over long distances. They depend on unique adaptations to communicate, locate food, navigate underwater, and/or understand their environment. Many marine animals rely on sound for survival. 24 bits : DVD-Audio, which can support up to 24-bit audio.Underwater sounds provide information about the surrounding environment-or soundscape-such as what marine animals are present or what human activities are taking place. 96,000 Hz : DVD-Audio, some LPCM DVD tracks, BD-ROM (Blu-ray Disc) audio tracks, HD DVD (High-Definition DVD) audio tracks.īit depth: 16 Bits (?) More : In digital audio, bit depth describes the number of bits of information recorded for each sample.

48,000 Hz : The standard used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on. Sampling Rate: 44,100 Hz (?) Search : Defines the number of samples per seconds taken from a continuous signal to make a discrete signal. It can not, for example, be used to sound an image taken outdoors. There is sometimes a little wind, some rumors, etc.Ī " indoor" sound usually contains a strong reverb. Used, for example, in virtual reality.Ĭonditions: Outdoor (?) A " studio" sound has been recorded in a reverb-free place.Īn " outdoor" sound contains disruptive elements. Ambisonic : aims to create a multi-channel sound space. Stereophonic : Is a method of sound reproduction that creates an illusion of directionality and audible perspective. Typically there is only one microphone, one loudspeaker.

This sound library meets the UCS 8.2 categorization. It provides consistency in a filename structure to make naming and categorizing easier for anyone who maintains their own personal or professional library. This is a list of fixed and consistent categories for classifying sound effects. UCS Category: Water / Wave ( WATRWave), Ambience / Seaside ( AMBSea) (?) The UCS, for "Universal Category System", is a public domain initiative by Tim Nielsen, Justin Drury and Kai Paquin, among others.
