Life and Love User ID: 1164971 United States 12/17/2010 11:46 AM Report Abusive Post Report Copyright Violation | Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound (including speech and music). It can be further categorized as a branch of Psychophysics. Quoting: Salt & LightThis is a fascinating subject. Years ago I was in a recording studio where they had set up a system for creating sounds from 1 Hz up to beyond our ability to discern. You could even see the huge speaker cone moving in and out once a second. There are visceral physiological responses to low frequency sounds that resonate with body cavities, and they sometimes lead to emotional responses. Thanks for the thread!

Thanks for the thread! +1 thats why humans are affected by music. Im a guitarist and can affect my families moods by what I play, not tempo, but by the tone of the notes. |

You can take two sound sources that differ slightly in frequency, and you will "hear" (more likely feel) the low frequency vibrations. Think about sitting in the back of a plane when the two engines are turning at slightly different frequencies. You'll feel a pulsating low frequency (called beat frequency).

Life and Love User ID: 1164971 United States 12/17/2010 12:11 PM Report Abusive Post Report Copyright Violation | i prefer basso profundo. i am very agitated with high freqency noices. i find comfort in the low tones. Quoting: Salt & LightWhat's interesting is that while we perceive sounds as combinations of frequencies, they are generated and transmitted as waveforms. It's our brain that converts the waveforms into event-driven spectra. Also, most of our musical instruments generate "one-dimensional" sounds, that is sounds whose fundamental and equally spaced harmonics are controlled by one dimension: the length of a violin string for example. The notable exceptions are percussion instruments which generate "two-dimensional" sounds, e.g., the head of a tympani. The harmonics of these are not equally spaced, so they affect us differently. There is also the possibility of three-dimensional and higher-dimensional sounds, but I don't know of any occuring naturally. We become like that to which we are devoted. - Choose wisely. |

Anonymous Coward User ID: 1198191 United States 12/17/2010 12:15 PM Report Abusive Post Report Copyright Violation | Remember this story ? Sony Corporation has successfully patented a technique for creating games where you can smell, taste and touch what's around you. Here's the sciencey bit: ultrasonic pulses are beamed at certain areas of the brain to transmit sensory information, creating "sensory experiences" - including aromas, sounds and images - for the brain's owner. The patent, which was awarded to Sony researcher Thomas Dawson, states that "The pulsed ultrasonic signal alters the neural timing in the cortex," if that means anything to you. Don't worry though, Sony aren't after sticking microchips in our heads just yet: "No invasive surgery is needed", apparently. Shame. The technique could also be used to help blind and deaf people "to view live and/or recorded images or hear sounds," the patent stated. Speaking to New Scientist magazine, neuroscientist Niels Birbaumer said he had examined Sony's patent and "found it plausible". Birbaumer works at the University of Tuebingen in Germany and has himself invented a machine that reads brain waves, enabling disabled people to communicate.

Quoting: Salt & Lighthave you guys heard of anti-noise devices? i wonder if it is some type of technology that uses low frequencies to cancel out higher frequencies. Most anti-noise devices have a small pickup and electronics that re-transmit an out-of-phase version of the original to null it out. (My laptop speakers won't do justice to the clips...

Life and Love User ID: 1164971 United States 12/17/2010 12:30 PM Report Abusive Post Report Copyright Violation | out-of-phase.... explain Quoting: Salt & LightA single tone can be represented as a simple waveform called a sine wave. It starts at zero, rises to a positive peak, falls back through zero, continues to a negative peak, and then comes back to zero again. That would be one cycle. "Out of phase" means that you generate an accompanying tone that starts at zero and falls to a negative peak first, etc., etc. The negative parts of the out-of-phase tone cancel the positive parts of the original tone, and the positive parts of the out-of-phase tone cancel the negative parts of the original tone. This effect occurs if you hook up one of your stereo speakers backwards. You get a cancellation in the middle of the room, because when one speaker is pushing air towards you, the other speaker is pulling air away from you.
