Environmental acoustics is concerned with the control of noise and vibrations caused by traffic, aircraft, industrial equipment, recreational activities and anything else that might be considered a nuisance.<ref name="auto"/> Acoustical engineers concerned with environmental acoustics face the challenge of measuring or predicting likely noise levels, determining an acceptable level for that noise, and determining how the noise can be controlled. Environmental acoustics work is usually done by acoustic consultants or those working in [[environmental health]].<ref name="auto2"/> Recent research work has put a strong emphasis on [[soundscape]]s, the positive use of sound (e.g. fountains, bird song), and the preservation of [[tranquility]].<ref>{{cite book|last=Kang|first=Jian|title=Urban Sound Environment|year=2006|publisher=CRC Press|isbn=978-0415358576}}</ref>
