These examples are programmatically compiled from various online sources to illustrate current usage of the word 'decibel.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2024 One reason why: The current noise law does not give a decibel limit for the low-frequency sounds - that thumping boom-boom bass loved by bars and loathed by the early-to-bed set. Emily Alvarenga, San Diego Union-Tribune, 31 Jan. (Examples from Wikipedia. 2024 San Diego’s $21 million quiet-zone safety system downtown, designed to reduce the decibel level of train horns at grade-level intersections, was approved by the City Council in 2010. We dont perceive this as a thousand times louder than the 50 dB of a washing machine, nor a hundred times quieter than the 100 dB of a jackhammer. Now, a 20 decibels sound is 100 times more intense than 0 decibels. This means that if 0 dB represents no sound at all, then 10 dB represents a sound that is 10 times louder.

It is not a linear scale, but a logarithmic one. Neil Senturia, San Diego Union-Tribune, 5 Feb. To understand how loud 60 dB is, we need to look at how the decibel scale works. using LAME for MP3) to a target ReplayGain value. This can be useful, for example, when encoding audio (e.g. The tricky part It’s not linear each 10 dB increase means the sound is actually 10 times more intense. This scale helps us compare sounds, from whispers (around 20 dB) to normal conversations (about 60 dB) and even louder things like concerts (around 120 dB). 2024 The level of certainty probably decreases as the decibel volume increases. For example, calculate the amplitude scaling factor if you want to adjust a sound waveform by -3dB or +6dB, or find out what the decibel difference would be if you scaled the waveform by 0.75. Decibels (dB) are a way to measure how loud or quiet a sound is on the decibel scale. Annie Midori Atherton, Washington Post, 6 Feb. 2024 For example, in the District of Columbia, the Noise Control Act outlines different maximum noise levels (measured in decibels) for various zones. Chloe Peterson, The Indianapolis Star, 17 Jan. 2024 The cheers and boos alternated loud as ever as the game started - the noise got as loud as 100 decibels, even in the nosebleed seats. Jared Ramsey, Detroit Free Press, 21 Jan. 2024 The team and supporters have spent the past week trying to make sure the atmosphere is even more intimidating this week and reset the decibel record at Ford Field in what will be the final Lions game in Detroit this season, win or loss. Sam Kmack, The Arizona Republic, 25 Jan. 2024 Buildings near those areas can’t make noise any louder than 68 decibels when sound is measured from 100 feet away, which is roughly as loud as a normal conversation. Recent Examples on the Web Dessner's introduction for the first surprise song prompted some of the loudest cheers of the night, measuring 120 decibels on my smartwatch.
