Library Soundproofing & Acoustic Solution

Does Your Library Exhibit the Following Phenomena (Problems):

Noise interference and echo problems

• Excessive echo and reverberation: Hard walls, ceilings, or large glass areas without sound absorption treatment will cause repeated reflections of sound, forming obvious echoes. For example, readers talking quietly or turning pages may be heard, disturbing others' reading.
• Background noise accumulation: The noise of equipment such as air conditioners and elevators is not isolated, or the sound of external traffic penetrates the windows, which will form continuous low-frequency noise and reduce the quietness of the environment.

Acoustic conflict between functional areas

• Interference between active and quiet areas: If the quiet reading area, group discussion area, or children's activity area is not distinguished by sound insulation design, the discussion sound may penetrate the peaceful area and destroy concentration.
• Failure of multi-functional space: If lectures or activities are required, if there is no preset acoustic diffuser or adjustable sound-absorbing panel, the speech will be blurred or the sound will be harsh.

Reduced speech clarity

• Information communication barriers: Broadcasting systems, electronic retrieval equipment, or staff notifications may be blurred by reverberation or background noise, affecting communication efficiency in emergency situations.

Health risks for readers and staff

• Long-term auditory fatigue: Continuous noise exposure may cause readers to experience tinnitus, decreased concentration, and even stress reactions.
• Staff occupational health: Front desk or lending office staff may face the risk of hearing damage due to long-term exposure to noisy environments.

Damage to brand image and user experience

• Decline in reputation: Noise problems may lead to loss of readers, especially affecting scholars or students who need to be highly focused.
• Functional limitations: Libraries that do not consider acoustic needs may not be able to host academic conferences or cultural events, limiting space utilization.

With CYATCO Acoustic Design, You Can Resolve the Above Issues:

1. Quiet environment

• Control background noise to ensure that the sound of turning pages and whispering does not interfere with reading.
• Control the signal-to-noise ratio (SNR) to improve voice intelligibility (soft communication can still be recognized);

2. Sound isolation and partition control

• Achieve sound isolation in different functional areas (such as quiet reading area, group discussion area, multimedia area) to avoid cross-interference;
• Control the sound insulation of walls and partitions to ensure that the sound of the discussion area does not overflow into the quiet area.

3. Precise control of reverberation time

• Control the reverberation time of the mid-frequency (500Hz) to avoid echo interference and avoid the environment being too quiet.
• Control the reverberation time of the low frequency (125Hz) to appropriately extend it to reduce the harshness of mechanical noise.

4. Sound field uniformity and comfort zone

• Control the difference in sound pressure level in the reader activity area to eliminate local noise hotspots or acoustic shadows.
• Avoid defects such as flutter echo and sound focusing, and optimize the sound field distribution through design.

5. Equipment noise control

• Reduce the noise of air conditioners and fresh air systems, and use vibration isolation pads and soundproof covers to reduce the noise of computers, printers, and other equipment.
