Sound is measured in decibels by a sound pressure level meter (SPL-meter).
A decibel meter is used to measure sound. It is a handheld device and can be used to quickly measure how loud certain sounds are. They are sometimes used to measure how loud a crowd is in sports.
You can estimate sound levels using smartphone apps that analyze audio frequencies, using online sound level calculators based on distance from the source, or by comparing the sound to familiar reference levels. However, these methods may not be as accurate as using a decibel meter.
