The phrase "acoustical material" is correct and usable in written English.
It can be used when referring to materials designed to absorb or block sound, often in the context of construction, music, or sound engineering.
Example: "The studio was designed with acoustical material to ensure optimal sound quality during recordings."
Alternatives: "soundproofing material" or "sound-absorbing material".
In 1950, he founded the Acoustical Materials Company in a garage in Hartford's North End.
Acoustical materials will dampen noise, and to encourage families to visit and spend time, the rooms will be spacious and equipped with extra storage.
Embodied production of archaeological knowledge that can be heard and felt creating sensory opportunities as well as acoustical science–– connects material archaeology with various forms of understanding.
Acoustical absorption of materials increased significantly with increasing SHPF content.
Taking inspiration from the materials of our daily life and the particular acoustical phenomenon that these materials produce, students will combinine their discoveries with Physical Interaction Design and Digital Signal Processing techniques to create works of art.
"Every room had acoustical foam and reflective material pasted on the walls," she said.
A physical analysis of the experimental data revealed that acoustical dissipation in this material is governed by inter-particle pores in the tested frequency range.
Expressions for the bulk acoustical properties of the material are obtained in terms of geometrical parameters volume porosity, tortuosity and effective fibre radius-and in terms of the mean internal flow speed; fluid properties and acoustic frequency are, of course, also involved.
The results demonstrated that acoustical characteristics of porous materials were exhibited by mixing with SHPF.
A novel approach is presented to study the acoustical properties of sintered bronze material, especially used to suppress the transient noise generated by the pneumatic exhaust of pneumatic friction clutch and brake (PFC/B) systems.
