Infrasound is characterized by an ability to get around obstacles with little dissipation. In music, acoustic waveguide methods, such as a large pipe organ or, for reproduction, exotic loudspeaker designs such as transmission line, rotary woofer, or traditional subwoofer designs can produce low-frequency sounds, including near-infrasound ...
[13] [14] Their research led them to conclude that infrasound at or around a frequency of 19 Hz, [2] [11] [15] has a range of physiological effects, including feelings of fear and shivering. [8] Though this had been known for many years, Tandy and Lawrence were the first people to link it to ghostly sightings.
Infrasound sensitive fibers are found to be simple bipolar cells in the auditory ganglion with a diameter of 1.6-2.2 μm at the axon and 0.9-1.2 μm at the dendrites. [19] They originate in the apical end of the cochlea and they are located near fibers that transmit low frequency sounds in the acoustic range.
Simon Vouet, Saint Cecilia, c. 1626. Research into music and emotion seeks to understand the psychological relationship between human affect and music.The field, a branch of music psychology, covers numerous areas of study, including the nature of emotional reactions to music, how characteristics of the listener may determine which emotions are felt, and which components of a musical ...
Infrasound is sound waves with frequencies lower than 20 Hz. Although sounds of such low frequency are too low for humans to hear as a pitch, these sound are heard as discrete pulses (like the 'popping' sound of an idling motorcycle). Whales, elephants and other animals can detect infrasound and use it to communicate.
Portal:Classical music/Quotes/10 Music is at once the product of feeling and knowledge, for it requires from its disciples, composers and performers alike, not only talent and enthusiasm, but also that knowledge and perception which are the result of protracted study and reflection.
Due to the wide range of signal properties and media they propagate through, specialized equipment may be required instead of the usual microphone, such as a hydrophone (for underwater sounds), detectors of ultrasound (very high-frequency sounds) or infrasound (very low-frequency sounds), or a laser vibrometer (substrate-borne vibrational signals).
In Musurgia Universalis he likens the creation of the world to the building of a great organ with six registers corresponding to the six days of creation on which God plays, creating harmony. [ 7 ] : 271 The illustration shows the elaborately-decorated organ with small circular panels illustrating each of the days of creation.
