He even rewired their bass boat for fun one weekend as a young teenager.

From his dad, he was able to learn irrigation, landscaping, car maintenance, basic electrical, and more. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago.Īt home, Kenny’s dad made the family budget stretch further by doing many DIY repairs around the house. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. It’s a logarithmic scale, which means that every increase of 10 dB represents a tenfold increase in sound energy. Imagine it as a magical tool that reveals the intensity of sound waves, from the faintest whisper to a thunderous roar. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. The decibel, often abbreviated as dB, is a captivating unit of measurement in the world of sound. Z-weighted is the flat frequency response of 8Hz to 20kHz (+/- 1.5dB), this is the actual noise that is made with no weighting at all for the human ear (Z for zero). Or for example as LCeq, LCPeak, LCE where the C shows the C-weighting. Kenny’s life around power tools started early. Measurements are typically displayed as dB (C) or dBC. While that might not sound like a direct line into the power tool industry, his analytical and scientific mindset help him design repeatable testing methods for Pro Tool Reviews’ head-to-head testing and offer highly objective comparisons in his reviews. There are tons of decibel equivalent examples out there to give you a general idea of how loud something sounds at a certain decibel level like the one we’ve included. 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. Sound Pressure Level and the Decibel Scale The reason sound pressure levels and decibels are so important is that it gives us a numerical scale to work with to help prevent hearing loss. For each 3 dB you drop, your sound pressure. By dropping 6 decibels, for instance, you first move 3 dB, and then another 3 dB. This simply means that for every 3 decibels you move up or down the scale from 0-194, you are adding or dropping 50 of your remaining sound pressure levels to your exposure. Sound pressure is the difference between the pressure from a sound wave and the ambient pressure of what the sound is traveling through (usually air for our purposes). The decibel scale is logarithmic, not linear. Simply put, decibels are a measure of the sound pressure level. We convert that into the more popular decibel scale or dB scale. Created by David SantoPietro.Watch the next lesson. Sound pressure level, or SPL, is a measurement of sound pressure that uses Pascals (Pa) as its unit of measurement. We often use this logarithmic scale to describe the intensity of sound. Since we’re going for a functional level of understanding and not preparing you for a final exam, I’m going to skip some of the fine details and focus on the general concepts.
