Sound transmission in the porpoise head
The Journal of the Acoustical Society of America, 1974By using small hydrophones implanted in porpoise tissue and an external sound source, pulsed sound was found to be channeled by the blubber coat and strongly reflected by blubber-muscle interfaces. Implants in the head showed concentration of sound in the proposed sound channel of the throat and jaws, complete acoustic isolation in the peribullary air ...

Transmission of Sound and Vibrations in Buildings
The Journal of the Acoustical Society of America, 1937Three problems are discussed: The insulation from air-borne sound by multiple walls. Structure-borne sound transmission. Measurements of vibrations by electrical apparatus. It is known that a single wall vibrates almost as a mass, provided its lowest natural period is much lower than the sound frequencies.

Ova knjiga je prije svega nastala s namjerom da prikaže put zvučne informacije od mjesta nastanka do primatelja informacije na mjestu slušanja. Nastala je kao skup predavanja iz predmeta Prijamnici koji se predavao na diplomskom studijskom programu FER-1 te predmeta Prijenos zvuka koji se predaje na preddiplomskom studiju po programu FER-2 i predmeta ...

Transmission of Sound of Explosions
Nature, 1922READERS of NATURE may be interested to know that a Commission appointed a year ago for investigating the transmission of sound of explosions is arranging for an experiment on this subject to take place on a day to be notified as soon after September 23 as the veather will permit.

The Transmission and Storage of Sound
2002There are two major deficiencies of sound from the point of view of making a musical performance enjoyable to a large number of people: it fades fast in relation to both distance and time. We have seen that the sound intensity drops very fast as we recede from the location of the sound source, and that the energy of the sound wave is quickly converted ...

In this chapter, the sound transmission system from a source to a listener is discussed. Considering time-domain processing in the auditory system, the sound source is described in terms of the autocorrelation function. The medium consisting of air and boundaries is expressed by the pressure transfer function or the impulse response. The hearing system

Sound Transmission Fundamentals
1990The science of acoustics involves the study and practical application of sound transmission in solid and fluid media. Although the subject is one of considerable scope, as figure 1.1 illustrates, our interest will lie particularly in applications involving sound transmission in the sea and in its underlying sediment layers and rock strata.

The transmission of sound through walls and barriers is an extremely important topic for noise control engineers. In this chapter we examine the basic principles of how sound passes through walls. The primary physical characteristics that influence sound transmission through walls are studied, including the importance of mass and how the bending ...
