متن کاملActive control of ultrasonic hearing in frogs.
Vertebrates can modulate the sound levels entering their inner ears in the face of intense external sound or during their own vocalizations. Middle ear muscle contractions restrain the motion of the middle ear ossicles, attenuating the transmission of low-frequency sound and thereby protecting the hair cells in the inner ear. Here we show that the Chinese concave-eared torrent frog, Odorrana to...

متن کاملUltrasonic Range Finding Sensor
During the research within the MAURO (Mobile Autonomous Robot) project (1995 – 1998) the research team from the 'Robot Control Systems' Laboratory has designed and realized an ultrasonic range finding sensor intended to be used in mobile robot navigation. The sensor has been successively improved and the design was adopted also by other research teams within the Automation Department being used...
متن کاملAirborne ultrasonic standards for hearing protection , 2008
The American Conference of Governmental Industrial Hygienists (ACGIH) increased the threshold level Values (TLVs) for airborne ultrasound and these levels were adopted by Occupational Safety and Health Administration (OSHA) in 2003. The European community, Australia and Canada have retained the more stringent levels that stemmed from reports of “ultrasonic sickness” in the 1960s. Ultrasound can...
