Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100 kHz. Elephants can hear sounds at 14â16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).
Several federal agencies were established during the Nixon Administration. These include: 1  OSHA (Occupational Safety and Health Administration) 2  MSHA (Mine Safety and Health Administration)  NIOSH (National Institute for Occupational Safety and Health)
The department as we know it now, a cabinet-level agency, was created by the Department of Education Organization Act, which President Jimmy Carter signed into law in 1979. The department officially opened in 1980 and started with an annual budget of $12 billion.
