Hearing range 60 decibels, the hearing range for the Senegal bushbaby is 92 Hz–65 kHz, and 67 Hz–58 kHz for the ring-tailed lemur. Of 19 primates tested, the Japanese macaque had the widest range, 28 Hz–34.5 kHz, compared with 31 Hz–17.6 kHz for humans. Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than humans or most dogs, detecting frequencies from 55 Hz up to 79 kHz. Cats do not use this ability to hear ultrasound for communication but it is probably important in hunting, since many species of rodents make ultrasonic calls.
60-meter band assignments with center frequencies 5373 kHz and 5405 kHz on a secondary non interference basis for propagation experiments with a maximum mean power not exceeding 27 dBW (500 Watts). Canada ( ITU Region 2 ): On Wednesday 22 January 2014, the Canadian regulator, Industry Canada (IC) released a decision to allow amateur radio operators to use the 5332 kHz, 5348 kHz, 5358.5 kHz, 5373 kHz and 5405 kHz (channel centre) frequencies on a no-interference, no-protection basis, 2.8 kHz bandwidth, same modes as U.S., 100W PEP maximum power. These are the same channels, modes and criteria as those available to US
