Although sound travels quite fast, it is still possible to calculate its speed in air. To do this, the time it takes a sound to travel a measured distance must be recorded. Either the distance ...

Velocity (and therefore pressure) is greatest mid-way between the maximum displacement of the vibrating body, and we can graph the resulting relationship between amplitude and sound pressure in the ...

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM ...

We plan to study other wave systems, such as large-amplitude ocean waves. "Surprisingly, sound waves and ocean waves have a lot in common: for example, the breaking of large-amplitude ocean waves ...

Acoustic phonetics is the study of the physical properties of speech and aims to analyse sound wave signals that occur within speech through varying frequencies, amplitudes and durations. One way we ...

polarization and amplitude of the applied sound wave. This approach offers far more rapid tuning than a mechanical grating, which must be moved or rotated to achieve tuning. “We're definitely ...

According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs in the HARMONIC SERIES, where the Fourier coefficients give the AMPLITUDE and PHASE angle of each component.

Ultrasound, like audible sounds, is transmitted by means of longitudinal waves. Ultrasound is used in medicine to break up kidney stones and gall stones. It is also used, in a process known as ...
