" as these values are essentially meaningless. They do not indicate how much light is projected from the lens but rather how much light is emitted at the source inside the projector before all the internal losses occur.
When interpreting this unit, it’s important to keep in mind that the decibel scale is logarithmic and not linear. As such, 3 dB increase in level doubles signal strength, while 10 dB increase in level is equivalent to a 10-fold increase in power. RSSI is a measurement of the power pre...
Noise on construction sites is typically measured using a decibel meter or noise dosimeter. A decibel meter, also known as a sound level meter, is an instrument that measures the intensity of sound in the air at a given moment. These meters provide immediate readings, allowing for immediate ad...
According to ESPN, even though the NHRA will let seismologists take meter readings, they've never recorded official decibel levels, and it's unlikely they ever will. It's all part of the mystique surrounding the sport. In 2010, an ESPN reporter scrambled around to find a sound meter capable...
Decibel Hi-Fi'somnidirectional kit speakerslook fun too, but are a bit expensive. Danish Sound Technologyhave kits, but you have to contact them for prices, which is not a good sign. The Fountek "Signature Series" kits look good for the money, though. ...
compressor. For example, a 1:1 ratio means that for every one decibel that goes into the compressor, one comes out. 2:1 means for every 2 decibels over the threshold (the point you want the compressor to engage), only 1 decibel is passed through. So 2 decibels are compressed into 1....
Sound intensityis measured using the decibel scale (dB), which relates the intensity of sound to the quietest sound we can hear. It's a logarithmic unit, which means an increase of 3dB equates to a doubling of sound energy and intensity. So an 88dB sound is twice as intense as an 85...

You can connect a cheap padlock alarm to your u-lock or chain lock so when it is moved, it will sound off a 100-110 decibel alarm. I would consider that more of secondary deterrent. There is also a bully pager alarm u-lock which is more a primary lock. The u-lock isn’t as ...
