Auditorium acoustics is a very specialized field at the intersection of acoustics and civil engineering.The two most important properties are Reverberation Control, and the control of Early Reflections.Wallace Clement Sabine was an US scientist acoustician who formulated much of the early foundation of acoustic measurements and of sound control in buildings.Before his time, the design of auditoria was very much a hit and miss situation. Some, such as the 'Big Music Hall' in Vienna was a very successful design, and was copied many times round the world. And much music was composed for this famous theatre. Other less successful attempts merely became warehouses.Chamber music is intended to be performed in small chambers (living rooms) of low reverberance, and the music for these will fail to be perfect in a larger space. Analogously, Cathedral music is intended to be heard in rooms with several seconds reverberation time, and indeed speech may be difficult, and has led to the style of speaking of a few words, followed by a pause to allow the echoes to decay.Sufficient. Leo Beranek is worth a look up, as is Harris, Cyril M.
power= energy time the time in seconds power= energy time the time in seconds
Power is energy divided by time, P=E/t.
The Mean Holding Time (MHT) can be calculated using the formula: [ \text{MHT} = \frac{\sum (t_i \times n_i)}{\sum n_i} ] where ( t_i ) represents the time held for each item, and ( n_i ) is the number of items held for that time. Essentially, MHT is the weighted average of holding times, taking into account the frequency of each holding time.
The formula would be when you take pi and divided it by a prime number such as 147 and then find the circurmfrence of a circle, take the radius and multiply the radius by the diameter, and then take the number you started with and add it to pi (3.14784634672435893746453... ect.) pi is an never ending number so just round it to 3.14 and then that will be your answer hope this helps
A Sabine is 1 metre sqaured of perfect absorption. Sabines formula for reverb time states: Reverb Time = (0.16 x Volume) / Absorption Therefore RT = (0.16 x 300)/13 = > 3.7 seconds. Reverb Time is usually calculated for each octave or third octave band of a frequency spectrum.
Factors that affect reverberation time include the volume of the room, the surface materials of the walls, ceiling, and floor, the amount of sound-absorbing materials present, and the shape of the room (e.g. irregular shapes can increase reverberation time). Temperature and humidity can also play a role in affecting reverberation time.
Reverberation is the persistence of sound in an enclosed space after the original sound has stopped. It can be controlled by adding sound-absorbing materials like curtains, carpets, or acoustic panels to reduce reflections, adjusting the room's layout to minimize hard surfaces that reflect sound, and using electronic equipment like equalizers or digital reverberation processors to manage the amount of reverberation in a space.
Reverberation - album - was created in 1990-05.
Reverberation - record label - was created in 2003.
the large obstacles and tall buildings etc causes the reverberation of thunder as it reflects sound and also causes multiple reverberation.
Yes, lecture halls typically have a longer reverberation period compared to smaller rooms. This is due to their larger size and hard surfaces, which reflect sound waves more efficiently. A longer reverberation time can enhance speech intelligibility if managed properly, but excessive reverberation can lead to echoes and make it difficult for listeners to understand spoken words. Therefore, acoustic design is crucial in such spaces to balance reverberation for optimal sound clarity.
Reverberation! :)

Whether a lecture hall is ideal for reverberation depends on how the hall was constructed and furnished, and on whether your need is for high, moderate, or low reverberation.
