Decibels, (derived from bels, old units which, like unwieldy farads, are rarely used) are convenient and user-friendly terms for expressing the ratio.The decibel scale is measured on a range from 0 dB, which is the threshold of human hearing, to 140 dB and beyond. At volumes above 130dB, the sound is painfully loud. Since we measure the loudness of a speaker in decibels, it is important to grasp the concept of a decibel and the decibel scale.Decibels (dB) are a way to measure how loud or quiet a sound is on the decibel scale. 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). The tricky part? It’s not linear; each 10 dB increase means the sound is actually 10 times more intense.There are three fundamental things that you must understand about the decibel. 1. The decibel employs a logarithmic scale, not a linear one. To help us understand the difference, let’s take a look at linear growth on a graph. A graph displaying a linear function: y = x.Hertz and Decibels. The relationship between Hertz and decibels allows a listener to measure the frequency and perceived loudness of any sound. The frequency or amount of air pressure change vibration is measured in Hertz. The resulting change in air pressure created through the vibrating object is measured in decibels.Sales effectiveness can be tricky to measure — and even tougher to improve.
