Raindrops are 40 decibels(分贝) while fireworks are 140 decibels. What about your headphones? They can go higher than 100 decibels. That's too loud. To protect your ears, keep your headphones at about half volume. And don't listen too long. About an hour a day is safe. Sounds Measured...
About 40 percent of the population is exposed to road traffic noise above 55 decibels(dB). There is a known link between noise and health problems such as heart disease, obesity and diabetes, but the impact on dementia is unclear. Researchers at the University of Southern Denmark ...

What are decibels? When we talk about sound levels, we talk in terms ofdecibels (dB). Like our hearing, the dB scale is logarithmic, so every increase of 10dB represents an increase in sound pressure by a power of 10 and an increase of perceived loudness by roughly a factor of two. ...
Meter soundMeter = new("MeasurementLibrary.Sound"); Gauge<int> gauge = soundMeter.CreateGauge<int>( name: "NoiseLevel", unit: "dB", // Decibels. description: "Background Noise Level" ); gauge.Record(10, new TagList() { { "Room1", "dB" } }); Out...
What instruments can measure sound decibels? Absolute zero is shown as 0 on which scale? What is the significance of absolute zero? What does the saturation point have to do with the dew point? What is absolute temperature? What is normalization in geochemistry? What is the dielectric constant...
How loud is a bird banger? “BANGERS” are a fused cartridge that travels out a distance of approximately 125 feet (42 (yards) before it explodes making a loud bang ofabout 160 decibelsthe sound equivalent of a gunshot. The deterrent effect of the banger noise is greater than the range ...
one measuring 8.6 inches by 9.85 feet and one measuring 11.8 inches by 9.85 feet. The only caveat is that this vacuum sealer is loud—approximately 78 decibels on its most powerful setting. Other than this minor flaw, the NESCO VS-12 represents the best value for what you receive and it'...
This system is complex because every three decibel increase equates to a doubling of sound intensity or acoustic power therefore the level of declared decibels is often not easily interpreted as to how loud something will be actually be experienced. Also, sound is context driven and the same ...
