      Noise Canceling Headphones

      Noise-canceling headphones are headsets that have the ability not just to block out noise but to cancel it using the properties of sound waves. Sound waves have compression and rarefaction characteristics similar to the crests and troughs of a transverse wave. They also have amplitude and frequency characteristics. These characteristics of sound waves are used

      What is a Hydrophone?

      A hydrophone is a type of microphone that is specifically designed to be used under water. Hydrophones depend on piezoelectric transducers to detect sound waves and other pressure waves coming from underwater vehicles, animals, and natural structures. Hydrophones were widely used in World War I, and II to detect U-boats (German submarines) and are still
