Sound Heath
Sound Heath, also known as Sound Common, is an area of common land in Sound, Cheshire, Sound, near Nantwich in Cheshire, England, which includes Heath (habitat), heathland, grassland, shrubland, scrub, woodland and wetland habitats. The majority of the area is designated a Site of Special Scientific Interest and a Local Nature Reserve. One of the very few lowland heaths in Cheshire, Sound Heath is a valuable habitat for heathland plants and animals, although its heathland character is currently under threat from the spread of trees and scrub. The common's ponds form one of the most important sites in the county for freshwater invertebrates. Three nationally rare species, rare or endangered species, endangered species have been found within the area: the Omphiscola glabra, mud snail (which is now one of the UK's most endangered freshwater creatures, having been recently recategorised as near threatened across Europe in the new IUCN European Red List of Non-marine Molluscs), great ...

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequency, frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
