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. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Kenny’s life around power tools started early.

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. 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). There are other decibel scales, like decibel-milliwatts (dBM), which measure electric power and have a reference level of one milliwatt, and decibel-watts (dBV), which measure output voltage level. Simply put, decibels are a measure of the sound pressure level. Technically, the units that capture the human perception of a broad range of sounds are A-weighted decibels (dBA). We convert that into the more popular decibel scale or dB scale. Sound pressure level, or SPL, is a measurement of sound pressure that uses Pascals (Pa) as its unit of measurement. 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.
