Sercel’s QuietSeis demonstrates ultra-quiet performance
PARIS -- CGG has announced that Sercel’s QuietSeis, which is based on next-generation MEMS (Micro Electro-Mechancial System) technology, is living up to its name after having successfully demonstrated low-noise performance during a recent series of field tests.
The sensor’s low noise floor was demonstrated at the LSBB laboratory, a low-noise underground science and technology center, in the south of France. Tests were conducted in a silo at a depth of 500 m below a mountain in a rural area with high acoustic shielding close to minimum Earth noise.
QuietSeis demonstrated an ultra-quiet performance of below 15ng/vHz, resulting in a high dynamic range of 128dB. This extremely low noise level corresponds to the quietest ambient noise detectable anywhere on Earth and is more than three times lower than that of MEMS sensors currently available on the market.
