dBsm dB (m 2) – decibel relative to one square meter: measure of the antenna effective area. dBm−1 dB (m −1) – decibel relative to reciprocal of meter: measure of the antenna factor. Decibels, (derived from bels, old units which, like unwieldy farads, are rarely used) are convenient and user-friendly terms for expressing the ratio.Source Code: Decibel meter with Arduino & LCD Display. This is the simple code that I have written in Arduino IDE. So you need to add the I2C LCD library and you need to define the A0 pin of the Arduino that we are using to detect the sound. #include <Wire.h>. #include <LiquidCrystal_I2C.h> // Library for LCD.Sound is measured in decibels and the quietest sound a human can hear is 0 dB. However, to determine what decibel level is too loud for neighbors, we need to look at how the decibel scale works. The decibel scale is linear. This means that 10 dB is a sound 10 times louder than 0 dB. But this is where it gets tricky. Decibel is a relative unit of measurement and each decibel is expressed as a ratio relative to a reference sound pressure, power, or intensity, or whatever quantity is being measured. For this reason, whenever we talk about decibels we use the word “level” meaning that the measurement is a ratio relative to a reference level.
