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)
In 2003, the Bush Administration sought to create a new agency, replacing the Office of Federal Housing Enterprise Oversight, to oversee Fannie Mae and Freddie Mac. In 1992 in the wake of the savings and loan crisis, and over concern similar lending problems would develop, the Office of Federal Housing Enterprise Oversight was created as part of the Department of Housing and Urban Development.
