A concert, theater, or auditorium hall should provide a spacious soundstage, ensuring
music is heard clearly and speech is understood in the back row. This is achieved
by balancing sound-reflecting and sound-absorbing surfaces and protecting the hall
from external noise. IN TECH STROY works with halls in educational institutions,
public buildings, and sports and entertainment complexes, including [Humo Arena](https://uzbuild.com/projects/)
and the Tashkent City Planetarium.

## Key figures

 * The optimal reverberation time depends on the purpose and volume: for a drama
   theater and an assembly hall for speech events, it is approximately 1.0 s; for
   a concert hall for symphonic music, it is significantly longer, up to 1.8–2.2
   s.
 * A multi-purpose auditorium needs a compromise between speech and music.

## Typical problems

 * Echo and flutter between parallel walls.
 * The voice from the stage is lost in the back rows.
 * The room is too dull after improper finishing with foam rubber or fabric.
 * Noise from the street, from the lobby and from the ventilation.

## Our solutions

 * **Sound-reflecting panels** near the stage and on the ceiling above it are Decoustic
   Original without perforation, Rockfon Sonar Bas.
 * **Sound-absorbing panels** on the back wall – [Decoustic](https://uzbuild.com/product-category/acoustic-materials/decoustic/),
   HERADESIGN, Rockfon Koral Tenor for low frequencies.
 * [Sonaspray](https://uzbuild.com/product-category/acoustic-materials/sonaspray/)**
   acoustic plaster** for complex architectural forms.
 * **Soundproofing and vibration insulation** of walls, ceilings and engineering
   equipment.

## How we work

 1. Analysis of the hall and usage scenario: music, speech, multipurpose.
 2. Calculation of reverberation and placement of materials.
 3. Selection of finishing materials in the hall design.
 4. Delivery and installation.

## Frequently asked questions

### How to improve the acoustics of an assembly hall?

Add sound-absorbing panels to the rear wall, sound-reflecting surfaces near the 
stage, and an acoustic ceiling in the auditorium. The amount of materials required
is calculated based on the volume of the hall and its intended use.

### Why did the hall start to sound dull after finishing?

Most likely, there’s too much sound absorption, or it only works at high frequencies(
fabric, foam). A balance of reflective and absorbent surfaces and materials that
work at low frequencies are needed.

### How do the acoustics of a concert hall differ from those of an assembly hall?

A concert hall for music requires a longer reverberation, while an assembly hall
for speeches requires a shorter one. Multipurpose halls are designed as a compromise.

### Is soundproofing necessary for the hall?

Yes, if there’s a noisy street, lobby, gym, or ventilation chamber nearby. Soundproofing
and vibration insulation protect the gym from outside noise, and adjacent rooms 
from the sound of the gym.
