What is Sound?
Sound is a form of energy created when air is disturbed in some
way causing changes in air pressure that radiate from the source of the sound in waves. Sound can be airborne; typically that of a human voice or impact: for instance the sound of heavy footsteps on a floor.

Sound waves vibrate at different rates or frequencies as they move through the air and are measured in cycles per second or Hertz; the faster a sound wave passes a given point, the shorter the wavelength and in turn the higher the frequency. Vibrations in the air caused by the sound determine how loud it is; the stronger the vibrations the greater the ’amplitude’. The length or duration of a sound i.e. it’s reverberation time or echo, is determined by the extent to which the energy is expended on contact with surfaces within a room.

Our production time is approximately 3 to 4 weeks. This allows for sufficient time to manufacture the products with quality and attention.
