REDUC Micro 17 Acoustic Foundation Floor Panels by Sound Suitable for use with both new and existing timber and concrete floors, the REDUC Micro is the perfect product for helping to minimise noise leakage. The acoustic overlay flooring is created using substrate layers of moisture-resistant MDF and fibreboard, separated by visco-elastic damping strips. The underside then incorporates a resilient layer of acoustic felt designed to provide mechanical isolation from the floor’s structure.

Johnson–Nyquist noise Johnson–Nyquist noise thermal noise, Johnson noise, or Nyquist noise is the electronic noise generated by the thermal agitation of the charge carriers usually the electrons inside an electrical conductor at equilibrium, which happens regardless of any applied voltage.

Electrostatic precipitator The positive ions reduce some of the negative charges on the dust layer and neutralize some of the negative ions on the 'charged particles' heading toward the collection electrode. Disruptions of the normal corona process greatly reduce the ESP& 39;s collection efficiency, which in severe cases, may fall below 50% . When back corona is present, the dust particles build up on the electrodes forming .

Vibration isolation Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations.. Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems.

Noise-canceling microphone Another technique uses two or more microphones and active or passive circuitry to reduce the noise. The primary microphone is closer to the desired source like a person& 39;s mouth . A second mic receives ambient noise. In a noisy environment, both microphones receive noise at a similar level, but the primary mic receives the desired sounds more strongly. Thus if one signal is subtracted from the .

Piezoelectricity Reduction of vibrations and noise Different teams of researchers have been investigating ways to reduce vibrations in materials by attaching piezo elements to the material. When the material is bent by a vibration in one direction, the vibration-reduction system responds to the bend and sends electric power to the piezo element to bend in the other direction.

Super Audio CD To reduce the space and bandwidth requirements of DSD, a lossless data compression method called Direct Stream Transfer DST is used. DST compression is compulsory for multi-channel regions and optional for stereo regions. This typically compresses by a factor of between two and three, allowing a disc to contain 80 minutes of both 2-channel and 5.1-channel sound.
