This question almost answers itself.
A paraboloid of revolution is formed in a rigid material. A microphone is placed at the focus. The axis of revolution is pointed at the sound.
The dish then concentrates the sound on the microphone.
These are used by spies, private detectives and ornithologists.

Is there a difference between a parabolic reflector and a parabolic dish?
A parabolic reflector typically refers to a curved surface that reflects or focuses light, sound, or radio waves to a specific point. A parabolic dish specifically refers to a type of parabolic reflector commonly used to collect or reflect electromagnetic waves, such as in satellite dishes. While they are both parabolic in shape, a parabolic dish is a specialized form of a parabolic reflector designed for a specific purpose.
What is meant by parabolic?
In mathematics, a parabolic shape refers to a U-shaped curve that is symmetric around an axis. Parabolic structures often exhibit properties like focusing parallel rays of light to a single point (as in parabolic mirrors) or guiding projectiles (as in parabolic trajectories).
Can you collect sound?
yes through your ears...but any other way is not possible
What does NOT exhibit parabolic motion?
Objects moving in a straight line or in circular motion do not exhibit parabolic motion. Parabolic motion is characterized by an object following a symmetrical path under the influence of gravity.
Name a type of reflector with a smooth surface?
A parabolic reflector is a type of reflector with a smooth surface that can collect and reflect light or sound waves to a single focal point.
A parabolic sound collecting dish science project?
this is a very good science project

What uses are there for parabolic mirrors?
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
What are associated with terrestial microwave transmissions?
Parabolic dish antennae Repeaters Transivers
What are assoicated with terrestrial microwave transmissions?
parabolic dish antennae repeaters transceivers
Do parabolic dishes hear through walls?
Parabolic dishes, such as those used in microphones, can capture sound from a specific direction due to their shape, which focuses sound waves onto a receiver. However, they are not designed to "hear" through walls. Walls can obstruct sound waves, dampening their strength and making it difficult for a parabolic dish to pick up sounds from the other side. Therefore, while they can enhance distant sounds in open environments, their effectiveness is significantly reduced when there are barriers like walls.
What is a beauty dish?
A beauty dish is a photographic lighting device which uses a parabolic reflector to distribute light towards a focal point.
What is the difference between directed antenna and parabolic dish?
about 40 db about 40 db
What is the Formula for calculating the surface area of a parabolic dish?
(2/3)*base*height
Which devices are associated with terrestrial microwave transmissions?
Parabolic dish antennae Repeaters Transceivers
Why might a parabolic reflector horn type microwave antenna be preferable to a parabolic dish type microwave antenna?
The reflector horn type antenna has greater "side lobe" rejection, directionality and sensitivity (efficiency) than a dish type.
How can you make a parabolic mirror?
Find an old dish network parabolic dish and buy some 3m solar reflective film. Cut the pieces into pie shapes and lay them in place over the interior face of the dish. Smooth out with a small squeegee. Trim edges from outside diameter. Voila!
