2. Acoustical engineering - Wikipedia

   en.wikipedia.org/wiki/Acoustical_engineering

   Other techniques to reduce product noise include vibration isolation, application of acoustic absorbent and acoustic enclosures. Acoustical engineering can go beyond noise control to look at what is the best sound for a product, [21] for instance, manipulating the sound of door closures on automobiles.

3. Noise control - Wikipedia

   en.wikipedia.org/wiki/Noise_control

   Acoustical wall and ceiling panels are a common commercial and residential solution for noise control in already-constructed buildings. Acoustic panels may be constructed of a variety of materials, though commercial acoustic applications will frequently be composed of fiberglass or mineral wool-based acoustic substrates.

4. Architectural acoustics - Wikipedia

   The typical sound paths are ceilings, room partitions, acoustic ceiling panels (such as wood dropped ceiling panels), doors, windows, flanking, ducting and other penetrations. Technical solutions depend on the source of the noise and the path of acoustic transmission , for example noise by steps or noise by (air, water) flow vibrations.

5. Acoustic panel - Wikipedia

   en.wikipedia.org/wiki/Acoustic_panel

   An acoustic board is a board made from sound absorbing materials, designed to provide sound insulation. [3] [4] Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy.

6. Acoustical measurements and instrumentation - Wikipedia

   en.wikipedia.org/wiki/Acoustical_measurements...

   Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...

   A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.
