In Stage (I), the various noise reduction
methods were implemented to produce the enhanced speech stimuli by using the three noise reduction
methods namely spectral subtraction, MMSE spectral amplitude estimator and subspace noise reduction
A Spray Based Crumb Rubber Technology in Highway Noise Reduction

Trelleborg is also looking to target specific vehicles with particular noise reduction
The CWM system basically can do a real-time noise reduction
process based on the above theories by a combination of high-speed STFT and high-resolution WT.
The effectiveness of the ITH's active noise reduction
technology was supported by a study completed in early December 2004 in the engineering psychology department of the U.
It will be up to regulations and the marketplace to decide when the technology is used before the noise reduction
benefit is realized.
Abstract: A multifunctional thermochemically cured coating which provides noise reduction
and weight reduction in combination with thermal insulating and corrosion resistant properties.
The community workshop to discuss noise reduction
will be held at 7 p.
The noise output of the MCS 40 has been reduced from 69 to 62 dB and the MCS 50 from 73 to 64 dB, a perceived noise reduction
of almost 50%.
work on a rumbling Teesside road will not happen until at least 2007.
With a Noise Reduction
Rating (NRR) of 33, the red, white, and blue Super Leights provide the highest level of hearing protection available.
Wireless network operators must deal with an array of voice quality issues, and Ditech's SX-24 and SX-30 products provide an effortless and extremely cost-effective means of deploying advanced noise reduction
and a whole host of voice enhancement technology into their networks," said Ray Caron, Ditech's Vice President of Marketing.
