For music, this must extend to much lower and much higher frequencies than for voice use only.
For example dogs and bats can hear sound at much higher frequencies than we can, and elephants much lower frequencies.
Ge is used because of the much higher carrier mobility compared to Si, allowing to design devices operating at much higher frequencies.
Most laser systems are active devices that operate in a manner very similar to microwave radars but at much higher frequencies (e.g., LIDAR and LRF).
This phenomenon has been attributed to a selection pressure for somatic hypermutations, which generally are observed at much higher frequencies in translocated copies than in ectopic copies.
All told, eastern earthquakes can shake areas ten times greater than comparable western ones.And they do so at much higher frequencies.
Further studies of the insects might give scientists some hints why the mating calls of many modern crickets have much higher frequencies, in the ultrasonic range beyond human hearing.
Results of the NCEP Evaluation Project Utilizing Novel E-Technology II (NEPTUNE II) survey indicated much higher frequencies of low-density lipoprotein (LDL) cholesterol goal achievement compared with frequencies observed in a similarly designed survey in 1997.
When an electrical current travels through a wire it creates an electromagnetic field, sending out waves in all directions rather like light, which is also a part of the spectrum but at much higher frequencies.
Prof Graeme Ruxton, from the University of St Andrews in Scotland, who also took part in the research, said: "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly.
At much higher frequencies, however, the response of the room is not dominated by a single mode, but rather the contributions from a much larger number of modes of roughly equal amplitude.
