Monitoring the global ocean through underwater acoustics Acoustic Monitoring Program: Underwater Acoustics Tutorial The following is a very brief overview of the basic principles of underwater acoustics. The tutorial is presented in twelve topics beginning with "What is Sound?". Choose Topic 1: What is Sound? 2: The Decibel Scale 3: Phase 4: Sound velocity 5: Sound pressure 6: Sound intensity 7: Sound pressure/intensity level 8. Conversion of dB from air to water 9. Source, path receiver model 10. Signal to noise ratio 11. SOFAR channel 12. Frequently used units 1. What is Sound? A propagating sound wave consists of alternating compressions and rarefactions which are detected by a receiver as changes in pressure. Structures in our ears, and also most man-made receptors, are sensitive to these changes in sound pressure (Richardson et al. 1995, Gordon and Moscrop 1996). The basic components of a sound wave are amplitude wavelength , and frequency The amplitude of a sound wave is proportional to the maximum distance a vibrating particle is displaced from rest. Small variations in amplitude produce weak or quiet sounds, while large variations produce strong or loud sounds. The

Since 1973 Castle has been a loudspeaker manufacturers in the truest possible sense with both design and manufacture of their world famous speakers housed entirely in one factory in Skipton England. Castle is rare amongst loudspeaker manufacturers in that they not only manufacture the drive units and electronic components found in their speakers but also the beautifully hand crafted real wood veneered cabinets used to enclose them. 30 years ago when Castle was formed the founding concept was to be a complete loudspeaker manufacturer and despite changing times and the globalisation of manufacturing Castle still retain this as the basis for the company.
