Noise levels For satiable communication, the average speech level should exceed that of an interfering noise by 6dB lower sound noise ratios are rarely acceptable (Moore, 1997).

This study in Germany found the average noise level in classrooms is 65 decibels.

A loud noise in the night scared him.

Kaki King rocks out to Pink Noise

So Bell employed an engineer to study those noises, to try and find out where they came from, with a view towards building the perfect hardware codec, which would get rid of them so they could think about using radio for the purposes of telephony.

The average reduction was 40 since the national peak.

A year later, I was listening to all the noise about the Middle East conflict.

This is because the shot noise of an optical communication channel is greater than the thermal noise of an electrical channel which, from information theory, means that more signal power is required to achieve the same data capacity.

(b) Refer to Annex 1 for details of peak year.

But, with real (inflation adjusted) house prices still 40 below the previous peak, a strong recovery for real estate (and the closely related construction industry) seems unlikely.

CBR Constant bit rate a Peak Cell Rate (PCR) is specified, which is constant.

But by reducing your energy use, pretty much at the peak times usually when you have you air conditioning on, or other times like that this generates the peak power at the peak usage time, so it's very complementary in that sense.

Peak time The peak time is the time required for the response to reach the first peak of the overshoot.

This channel is often used by theorists because it is one of the simplest noisy channels to analyze.

The peak ratio and the subsequent downward trajectory depend crucially on the assumed pace of economic growth.

3 Where (p) stands for peak, (e) stands for electric and (th) stands for thermal.

So we have to be very concerned about when the noise in habitats degrades the habitat enough that the animals either have to pay too much to be able to communicate, or are not able to perform critical functions.

El Nahual is in favor of this new project because , it is quiet, does not contaminate, promotes the use of public transportation, etc.

He was also to receive 20 of the gross against his salary from the Rush Hour 3 .

In 2007, nearly 9,000 vehicles crossed the bridge every hour at peak flow.

As the temperature increases, the peak shifts to shorter wavelengths, producing first a red glow, then a white one, and finally a blue white colour as the peak moves out of the visible part of the spectrum and into the ultraviolet.

Now think about it. This is an amazing thing That in this frequency range where whales communicate, the main source globally, on our planet, for the noise comes from human ships, thousands of human ships, distant, far away, just all aggregating.

But culminating and that's where this hooks into the theme of my little talk which is suspended from the cantilevered portion of the building.

Well, I think out ahead of us a few decades is peak gas, and beyond that, peak renewables.

Annual growth in the consumer price index peaked at 6.5 in July 2011.

The Cultural Revolution marked the climax of class extermination practiced by the Party during the 1960 s.

The closest alpine peak, the 1,972 metre high Untersberg, is less than from the city centre.

Off peak Peak demand is considered to be the opposite to off peak hours when power demand is usually low.

Rewa reached its initial peak intensity as a Category 4 tropical cyclone on 2 January.

We are in favour of studies on the impact of man generated ocean noise on fisheries and ecologically related species.

The purpose of these policies is to reduce the number of vehicles on the roads and thus reduce rush hour traffic intensity.

By August 2005, they had lost about 30 per cent compared to their peaks.

Seasonal variations are considerable, November and March being the peak times for fish harvesting.

Photography carries a power that holds up under the relentless swirl of today's saturated, media world, because photographs emulate the way that our mind freezes a significant moment.

You take all of the conflict, all of the chaos, all of the noise, and out of that comes this precise mathematical distribution of the way attacks are ordered in this conflict.

After a few more ineffectual minutes of trying to be heard above the din, the Speaker adjourned Parliament again.

Another register controlled the period of a pseudo random noise generator, while another controlled the mixing of this noise into the three primary channels.

The point at which the economy stops growing is called the peak, and the point at which it stops contracting, the trough. The period from the point at which the economy starts to grow again until the point at which it reaches the previous peak is called the recovery.

The results are undeniable at peak times, mini bus taxis hold 65 of the entire commuter market.

We take it for granted that health clubs charge more for memberships that include peak hours.

This is the noise that Penzias and Wilson heard the oldest sound that you're ever going to hear, the cosmic microwave background radiation left over from the Big Bang.

A key advance in audio fidelity came with the Dolby A noise reduction system, invented by Ray Dolby and introduced into professional recording studios in 1966.

In an even more radical stance against consumerism, the company placed a Don't Buy This Jacket advertisement during the peak of shopping season.

The World Health Organization estimates that a quarter of Europe's population is having its sleep degraded by noise in cities. We can do better than that.
