Audio Reproduction

Audio reproduction refers to the recording of sound waves and then recreating them with or without sound effects.

As early as the 18th century, efforts were on to record sound and to reproduce it. This would be a major breakthrough, enabling the reproduction of songs, speeches and even music from instruments. When Thomas Edison came up with the phonograph in 1877, many were the applications of the same.

The phonograph was the precursor to the more known gramophone and it was the first instrument to reproduce recorded sound. It worked by etching on waveforms onto a rotating disc. The sound was then reproduced by the vibrations caused on a stylus as it retraced the etched grooves on the disc.

Today, the sound is recorded by a transducer that picks up the variations in atmospheric pressure caused by the sound waves and converts them into an electrical signal.

The recording of sound can be either analog or digital. An analog signal is one which looks like a sine wave. It is a continuous signal. On the other hand, a digital signal is one that is non-continuous. It is represented by a discrete set of values.

With all the latest technology that we have at hand today, the focus is on bringing out the same user experience as we would get if we were present at the original environment where the sound waves were originally produced.

To add to the crystal clear high-quality sound recording of today, all noise and disturbances must be eliminated. It is thus a necessity that vibrations during recording and during the reproduction, from around the equipment as well as from the equipment itself be removed.

Ideally, all loudspeakers and other audio equipment must be placed on vibration isolating platforms. This absorbs the vibrations from the device and thus enhances the listener’s experience to a significant degree.

Vibration isolation can also help with countering the effects of resonance. Resonance can occur when the frequency of the vibrations due sound coincides with the natural frequency of the surface or nearby object and this, in turn, causes a synchronous vibration of the same. The amplitude of vibration increases rapidly due to resonance and this can be a potential threat to the stability of the system. By vibration isolation, the surface absorbs the vibration from the source and thus prevents it from causing further problems to neighboring devices.

We realize that each lab or studio has unique needs and so we can help you by coming up with anti-vibration techniques specifically suited to your environment.
