A very important but little known acoustical phenomena is the Inverse Square Law. As a sound wave propagates spherically‚ the sound energy is distributed over the ever-increasing surface diameter of the wave front surface. So‚ when the distance from the source is doubled‚ the energy carried by the sound is spread over double the distance in all directions‚ or four times the original area. This means that the intensity will be reduced to a quarter of the original distance. For example‚ at three times

Journal Article Your vocal presentation is very important when delivering a speech. Vocal delivery includes rate‚ volume‚ and pitch. Vocal delivery helps us engage and interest the audience and it ensures that our ideas are communicated clearly. Rate of speaking is how fast or slow you speak. The rate of speaking should be in middle as speaking too fast the audience will not absorb all information and speaking too slow will lose audience attention. To control rate of speaking one should practice

The approach I used in unit 5 was a generic design which is flexible in nature with a basic layout planned so it can be easily molded‚ or modified to fulfill a variety of needs or applications. The wireframe associated with the design is shown without a supporting structure. The associated structure will be dictated by its application and placement. Part 2: Non-Speech Sounds.

Ultrasound Ultrasound is an imaging technique that uses high frequency sound wave and echoes. There are different kinds of ultrasound they are two-dimensional image‚ 3D ultrasound imagining‚ and Doppler ultrasound. Doppler ultrasound is based on the Doppler effect. (Doppler effect is whenever relative motion exists between a source of sound and a listener and the frequency of the sound heard by the listener sounds different compared to the frequency when there is no motion.) The frequency of the

There will be a net force from the pressure to push the piston back out. Since gas has mass it can support oscillations and waves. 2.2 Traveling Sound Waves
