The sensiBel technology was developed over a period of SINTEF, resulting in a 15 deciBel (dB) reduction in microphone noise. Today’s low-cost silicon microphones in mobiles, laptops, headphones, etc. are very noisy – because they have to be so small. A video recorded with your mobile will sound quite noisy if you record in a quiet room. With the sensiBel microphone, we can maintain the small size and low cost, with almost three times less hearable noise.
