A noisemaker is something intended to make a loud noise, usually for fun. Instruments or devices commonly considered "noisemakers" include: pea whistles; air horns, composed of a pressurized air source coupled to a horn, designed to create an extremely loud noise; fireworks, such as firecrackers, bottle rockets, bang snaps and others
Individuals with exploding head syndrome hear or experience loud imagined noises as they are falling asleep or are waking up, have a strong, often frightened emotional reaction to the sound, and do not report significant pain; around 10% of people also experience visual disturbances like perceiving visual static, lightning, or flashes of light.
The sufferer becomes anxious to get away from the source of the loud sound and may get headaches. [1] It may also be related to, caused by, or confused with hyperacusis, extreme sensitivity to loud sounds. [5] Phonophobia also has been proposed to refer to an extreme form of misophonia. [6]
Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]
The sound is used on trailers for THX-certified movie theaters, home video releases, video games, and in-car entertainment systems. The Deep Note was partially previewed on the opening track of the 1983 album The Digital Domain: A Demonstration, where it was included among sound effects that were combined with the Deep Note itself.
A groan tube is a toy that when turned on one end, makes a distinct "groan" sound. This is due to a noise maker in the tube that vibrates in the air as it falls, making the noise. [1] The groan tube was invented in the early 1960s by Japanese toy manufacturer Kureo. [2] [unreliable source?] The toy was first sold as 'Magic Noise Tube ...
Two-dimensional slice through 3D Perlin noise at z = 0. Perlin noise is a type of gradient noise developed by Ken Perlin in 1983. It has many uses, including but not limited to: procedurally generating terrain, applying pseudo-random changes to a variable, and assisting in the creation of image textures.
The single noise-maker however would work effectively only if the torpedo was equally sensitive to sounds from both the front and rear. If a torpedo passed directly over the noise-maker from the rear the ship itself would be directly ahead, if the torpedo had a reduced sensitivity to noise from behind, it might ignore the greater output from ...
