An acoustic mirror is a passive device used to reflect and focus (concentrate) sound waves. Parabolic acoustic mirrors are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor sporting events.

The acoustic mirror A sketch of the acoustic mirror. Il-Widna is a large acoustic mirror located in Magħtab, Malta.' [1] The colloquial name of the acoustic mirror refers to Ear in Maltese. The mirror is 200 feet (61 m) long, approximately the same design as the sound Mirror in RAF Denge. [2]
In an SMR structure acoustic mirror(s) providing an acoustic isolation is constructed between the resonator and the surrounding like the substrate. The acoustic mirror (such as a Bragg reflector) typically consists of an odd total number of materials with alternating layers of high and low acoustic impedance materials. The thickness of the ...
Major William Sansome Tucker OBE [1] (1877 Kidderminster, Worcestershire - 1955 Guelph, Ontario, Canada) [2] was an English pioneer in acoustical research and inventor of the acoustic mirror [3] Early life
Other acoustic scientists advance understanding of how sound is affected as it moves through environments, e.g. underwater acoustics, architectural acoustics or structural acoustics. Other areas of work are listed under subdisciplines below. Acoustic scientists work in government, university and private industry laboratories.
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
Parabolic microphone used at an American college football game. A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves.
