What is the combination of many small echoes that occur very close together?
The combination of many small echoes that occur very close together is referred to as "reverberation." This phenomenon happens when sound waves reflect off surfaces in an environment, creating a series of overlapping echoes that can blend together. Reverberation is commonly experienced in large spaces, such as concert halls or cathedrals, where sound can bounce off walls, ceilings, and floors, enhancing the overall auditory experience.
Describe ways that echoes are used in measurement?
The speed of sound is the distance travelled by the sound waves in the time between the original sound and the echo. For a direct echo, the distance travelled is double the distance to the reflecting surface.
How do you minimized water?
You can minimize water pollution by not littering or dumping things into the water
Why should a primary standard be of high molecular weight?
so that weighing errors are minimized
Can echoes travel faster than light?
No. Nothing can travel faster than light.
Name any two oldest cinema halls in delhi?
regal cinema 1932
Why are echoes undesirable in large halls?
Echoes are undesirable in large halls because they can distort or overlap with the original sound, making it difficult for listeners to understand speech or music clearly. This can also create a distracting and unpleasant listening experience. To minimize echoes in large halls, acoustic treatments such as sound-absorbing materials or diffusers are often used to absorb or scatter sound waves and reduce reverberation time.
Where Can you get movie screen?
Inside a cinema hall! Cinema halls/complex get their screens from various suppliers, such as B&H in Los Angeles.
How reflection of sound is prevented in large auditorium or cinema hall?
To prevent sound reflection in large auditoriums or cinema halls, acoustic treatments such as sound-absorbing materials like acoustic ceiling panels, wall panels, and carpets are installed. These materials absorb sound waves, preventing them from bouncing off surfaces and causing echoes. Additionally, the use of diffusers can help scatter sound waves and reduce reflections.
Cinema halls list in andhra pradesh?

Why can you hear echoes in long galleries and big halls?
You can hear echoes in long galleries and big halls because sound waves travel over distances and reflect off hard surfaces like walls and ceilings. When a sound is made, it bounces back to the listener after a short delay, creating the perception of an echo. The size and shape of these spaces allow sound waves to travel further before dissipating, enhancing the echo effect. Additionally, the absence of soft materials that absorb sound contributes to the clarity and duration of the echoes.
What three things are applications of an echo?
Medical imaging: Ultrasound uses echoes to create images of internal body structures. Sonar systems: Echoes are used to detect and locate objects underwater, for navigation, mapping, and fishing. Acoustic design: In architecture and engineering, echoes are managed to improve sound quality in buildings like concert halls and theaters.
Multiple echos in a concert hall?
In concert halls the walls are made out of acoustic materials. The materials, as well as the amplifier may result in multiple echoes in a concert hall.
How many cinema hall there are in Bangladesh?
On Historical aspects: Bangldesh Cinema hall (movie theaters) are dying. In 1990-91 the number of cinema halls were around 1230. But in 2010 the number has decreased to 742. Out of 44 cinema halls in Dhaka 33 are surviving. Huge building were erected in their place. Big names like, Gulistan, Shyamoli, Naz, Lion, Star, Shabistan, Tajmahal cinema etc. went into oblivion. There are some 4 or 5 star movie theaters available: Star Cine complex, Balaka, Modhumita. All are in Dhaka. Reasons: No good movies are made in Bangladesh.

When an echo considered useful?
An echo is considered useful in various contexts, such as in medical imaging (ultrasound), where it helps visualize internal organs and structures by reflecting sound waves. In navigation, such as sonar, echoes assist in detecting objects underwater. Additionally, in architectural acoustics, echoes can enhance sound quality in concert halls when properly managed. Overall, echoes provide valuable information across multiple fields by allowing the analysis of reflected sound waves.
