A decibel limiter, also known as a decibel killer, is a device designed to reduce the sound level of a vehicle's exhaust system. This is achieved by absorbing, muffling, or redirecting sound waves, thereby decreasing the noise produced by the exhaust. Decibel limiters are often used to mitigate noise pollution and comply with legal sound standards in specific areas.These devices are particularly popular among car and motorcycle enthusiasts looking to enhance their vehicle's performance without significantly increasing the noise level. A decibel limiter can help control the sound of a sport exhaust or a more powerful engine system, allowing the vehicle to deliver performance benefits while avoiding excessive noise disturbance.The purpose of a decibel limiter is to keep sound emissions within acceptable limits, ensuring that vehicles comply with legal sound standards and contribute to a less disruptive environment for nearby residents.
