støjmålere
Støjmålere, also known as sound level meters, are instruments used to measure the intensity of sound. They are essential tools for environmental monitoring, occupational safety, and acoustic analysis. A basic støjmåler consists of a microphone, an amplifier, and a display. The microphone converts sound pressure waves into electrical signals. The amplifier then processes these signals to a measurable level, and the display shows the sound pressure level, typically in decibels (dB).
Different types of støjmålere exist, ranging from simple analog devices to sophisticated digital instruments with advanced
The accuracy of a støjmåler is crucial and is often defined by international standards such as IEC
