Soft materials in cinema halls help avoid echoes, interference, and standing waves, improving sound quality.
The phenomenon characteristic of sound waves that is attempted to be avoided by covering the walls and ceiling of cinema halls with soft materials like carpets is echo. Echo is the reflection of sound waves off surfaces that can cause repetitive and delayed sound perception, which might disrupt the clarity and quality of the audio experience.
By using materials that absorb sound rather than reflect it, the interference caused by echoes is minimized, enhancing the acoustics of the space and improving the overall sound quality for the audience.
Additionally, the design of auditoriums with sloping surfaces and diffusive materials aims to reduce standing waves and undesirable acoustic effects like echoes, creating a more pleasant listening environment.
