because it allows only direct sound to reach the audience .they are even made up of sound proof wall with the concept of two walls and a gap between them so that the sound does not go out and disturb the other people and in another hand to much echo and reverberation makes the sound muddled and we cannot hear anything (dialogues )etc .clearly.therefore , sound absorbing materials are kept in the cinema halls.

Why are concert halls often designed as round or curved auditoriums?
hi erinSimply to improve the way travels throughout the room.The sound of music in halls (acoustics or reverberation) will be altered due to the timing of echoes within the hall and the rate at which they decay away. Echoes with a long delay are generally undesirable and confusing to the ear, so large sheets of hard material (baffle boards) are suspended within the hall and used to reflect sound (make echoes) at short delay times from the stage, rather than allowing the sound to travel as far as the walls or ceiling to create echoes at long delay times. Baffle boards may also be curved in order to disperse echoes to make them less obvious to the ear. Soft absorbent materials are used to prevent echoes from distant parts of the hall which might otherwise create echoes with long delay times. The soft furnishings of seating, carpeting and even the people in the audience will absorb sound and reduce echoes. The essential quality of a concert hall is called the "reverberation characteristic" which is a measure of the timing of the echoes and the rate at which they die away. In a concert hall, a certain amount of reverberation is desirable and pleasing to the ear, while in a recording studio reverberation is prevented as much as possible. Concert halls are regarded generally as having "lively" acoustics while recording studios are regarded as having "dead" acoustics.
What is the sound proofing material on the walls of the Bones TV show interrogation room?
Megaplastic. What is it? Why?
When was Herkie Walls born?
Herkie Walls was born in 1961.
How are echoes minimized in cinema halls?
Cinema halls are designed with sound-absorbing materials like carpets, drapes, and acoustic panels to reduce echoes. Additionally, strategic placement of speakers and sound diffusers helps distribute sound evenly throughout the hall, minimizing echoes and improving sound clarity for moviegoers. Proper calibration of audio equipment also plays a crucial role in minimizing echoes in cinema halls.
Which is the best sound absorbing materials in partition walls?
glass wool
What is the sound like in bass concert halls?
In bass concert halls, the sound is amplified by the size of the open empty room. The sound reverberates off the walls to make it sound louder and deeper than it really is.
Reverberation in conceret halls is caused by what kind sound?
Reverberation in concert halls is caused by the reflection of sound waves off the walls, ceiling, and other surfaces in the space. These reflected waves mix with the direct sound from the performers, creating a lasting and rich acoustic environment that can enhance the listening experience.
Why is sound - absorbent material is used on the walls in auditoriums?
Sound absorbing material is used in the walls of auditoriums to stop undue reflection.It is also used in offices,aeroplanes,hospitals and factories to cut down noise.
Why do theatres and cinemas have thick curtains hanging along the walls?
The curtains provide attractive sound deadening so that it doesn't echo in the theater. Some theaters just use other sound absorbing methods but the curtains are something of a hold-over from the older theaters where plays and concerts were performed in the past and have a nice appearance.
How effective are sound insulation walls in reducing noise pollution in residential areas?
Sound insulation walls can be effective in reducing noise pollution in residential areas by blocking or absorbing sound waves, thereby reducing the amount of noise that enters a home. However, the effectiveness of these walls can vary depending on factors such as the materials used, the design of the walls, and the level of noise being generated.
How can I effectively dampen sound in a room?
To effectively dampen sound in a room, you can use sound-absorbing materials like acoustic panels, curtains, rugs, and furniture. Additionally, sealing gaps and cracks in walls and windows can help reduce sound transmission. Placing bookshelves or other objects along walls can also help absorb sound waves.
What is the best placement for an upright piano to ensure optimal sound quality and performance, while also considering that it should not be placed against a wall?
The best placement for an upright piano to ensure optimal sound quality and performance is in the center of a room, away from walls. This allows the sound to project evenly and prevents the walls from absorbing the sound.
How could you reduce the echoes in a music studio?
By lining the walls and other hard surfaces with curtains, drapes, foam panels, or other sound absorbing materials.
How do anechoic chambers work?
Anechoic chambers work by absorbing sound waves to prevent reflections. This is achieved using sound-absorbing materials on the walls, ceiling, and floor to minimize reverberation. The goal is to create a space with minimal sound reflections, allowing for accurate acoustical measurements and testing.
What are the benefits of noise barrier walls in reducing sound pollution in urban areas?
Noise barrier walls in urban areas can help reduce sound pollution by blocking and absorbing noise from sources such as traffic, construction, and industrial activities. This can improve quality of life for residents by reducing stress, improving sleep, and protecting hearing.
