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.
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.

a very long time
ricolas are the best. they have the more natural taste (made out of herbs) and in he long run are better .halls are quick relief but wont last that long

"Hear" doesn't have an "a" sound at all; it has a long "e" sound.
