What is the decibel scale4/10/2024 ![]() ![]() 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. This can be useful, for example, when encoding audio (e.g. 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. Emily Alvarenga, San Diego Union-Tribune, 31 Jan. Useful for converting decibals into amplitude scale factors. There are two major points to keep in mind when it comes to the dB scale: the actual sound pressure level and how loud something sounds. 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. Sound Pressure Level and the Decibel Scale. Neil Senturia, San Diego Union-Tribune, 5 Feb. 2024 The level of certainty probably decreases as the decibel volume increases. 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. 12 dB FS is 12 decibels lower than the maximum level possible in a fixed point digital system. Digital audio levels are negative numbers (-12 dB FS, -20 dB FS, etc.). Chloe Peterson, The Indianapolis Star, 17 Jan. If a digital audio signal exceeds 0 dB Full Scale in a fixed point system, digital clipping will occur. With every 10dB increase, there is a tenfold rise in sound intensity, leading to a perceived doubling of loudness. It operates on a logarithmic scale, comparing the sound’s pressure level to a reference level. 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. In regards to sound, a decibel (dB) is a unit of measurement used to gauge the intensity or loudness of sound. Jared Ramsey, Detroit Free Press, 21 Jan. Neither choice is perfect, but the physical decibel meter is more. ![]() You can either use a physical decibel meter, or an application on your phone (here’s a highly-rated one for Android and a NIOSH-developed one for iOS ). 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. The easiest and most accessible way to measure how loud your headphones are is by using a sound pressure level (SPL) meter. 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. ![]()
