All of our products receive high NRC ratings, making them the perfect choice for bringing peace to your space. It’s important to note that the effectiveness of acoustic products depends largely on the size of the space and how the product is installed. The NRC is calculated by averaging the various measurements and rounded off to the nearest 0.05.Right-click the audio region and select de-noise. Doing so is easy thanks to BandLab’s built-in intelligent algorithm.
Once the initial measurement is taken, the product being tested is placed in the same test lab, and the sound absorption is measured at four different frequencies. De-noise your short voiceover clip to remove any low-level background hum.To begin the test, an initial measurement is taken by transmitting a noise signal into the room and the equipment takes a measurement of how much sound was absorbed.There are a few different ways to determine NRCs, the following is an explanation of how our products are tested for NRC using the ASTM Standard Test Method for Sound Absorption.Ī special sound test lab room specifically designed for measuring sound absorption is equipped with a microphone and fancy equipment that measure sound frequencies. TestingĬalculating the NRC for an acoustic product is no small task. At 1 NRC, 100% of the sound is being absorbed by the acoustic product, and no sound is being reflected back into the room. Our AI noise removal algorithm can automatically remove undesirable background noise of any kind Here's proof.
