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.
Radio in the Republic of Ireland commercially in Ireland, and the first attempt to license such since 2002; as well as what will amount to four stations easily receivable in most of Dublin city and county. It is expected these may be the last commercial analogue services to be licensed, as the FM band will be highly saturated in Dublin and the midlands of Ireland. Digital Radio Mondiale (DRM) on Ireland's many unused ITU-allocated medium wave frequencies is expected to be the next round of licensing, particularly as some of these allocations are 15 to 20 kHz wide, which is enough for FM-alike quality with the
