Mechanical Waves One important characteristic of sound waves is that they are mechanical waves. This means that they travel through a medium. Sound waves can travel through all sorts of mediums.Instead the wave speed changes gradually over a given distance. The speed of a sound wave in air depends on the temperature (c=331 + 0.6 T) where T is the temperature in o C. Often the change in the wave speed, and the resulting refraction, is due to a change in the local temperature of the air. For example, during the day the air is warmest ...Low frequency sound waves typically cover the 100-150Hz range and are, for example, the type of waves that come from a stereo subwoofer. However, many noise sources produce bass frequencies. Sound waves are caused by vibrations, either through the air or solid materials.

Sound is a type of mechanical wave which moves by oscillating the particles of the medium in which it is travelling. We use our ears to receive sound signals, but there is a limitation to it. Not all the vibration can be perceived by our ears. bain case styleSound is a longitudinal, or compression wave. A region of slightly more compressed air is followed by a region of slightly less compressed air (called a rarefaction). When the compressed air is behind the balloon, it pushes it forward, and when it is in front of the balloon, it pushes it back.When it lives outside our brain, it consists of mechanical, acoustic waves of compressed and rarefied molecules of air (i.e., sound); when it exists inside our brain, it consists of electric waves that are the channel of communication for neurons. Waves: In either case, this is the concrete stuff of which language is physically made.The five main characteristics of sound waves include wavelength, amplitude, frequency, time period and velocity. Wavelength: The most important characteristic of sound waves may be the wavelength. Sound consists of a longitudinal wave that includes compressions and rarefactions as they travel through a given medium.A sound wave is the pattern of disturbance caused by the energy travelling away from the source of the sound. Sound waves are longitudinal waves. This means that the propagation of vibration of particles is parallel to the energy wave propagation direction. When the atoms are set in vibration they move back and forth.Sound waves.
