Many people don't realize how much a 30 or 40 dB ratio is. A piece of electronic equipment with a S/N ratio of 80dB may be good enough for all but the best systems. Example: If you were looking at 2 amplifiers and one had a S/N ratio of 102dB and the other was rated at 80db. You'd probably think that the amp with the higher ratio was quieter ...Does the AMD 13 ship with the newer 80db speakers or the “original” ones? Looking at the speakers I can’t tell which model they are.

An alarm clock sits at around 80 dB, though this can be misleading as alarm clocks are sudden, so they feel louder. Heavy traffic in a city is around 80 dB level too. On the other extremes, firearms are at about 150 dB.A signal-to-noise ratio compares a level of signal power to a level of noise power. It's most often expressed as a measurement of decibels (dB). Higher numbers generally mean a better specification since there's more useful information (the signal) than unwanted data (the noise). For example, when an audio component lists a signal-to-noise ...80分贝可以认为是繁忙汽车道路中的声音；80分贝则是介于闹市区以及汽车穿梭的马路上之间的声音大小。. 70分贝相当于走在闹市区；85分贝汽车穿梭的马路上。 分贝（decibel）是量度两个相同单位之数量比例的计量单位，主要用于度量声音强度，常用dB表示。 “分”（deci-）指十分之一，个位是“贝 ...The Speaker Kit - Original has more accurate audio fidelity while the Speaker Kit - 80dB is louder.
