♦In terms of sound insulation and indoor acoustics, phone booths should serve as a sanctuary for employees seeking quiet spaces. This requires them to effectively block external noise while also containing noise generated within the booth.

Testing phone booths in office environments allows evaluation of their effectiveness in blocking external noise and preventing sound leakage, ensuring employees receive the required privacy and tranquility.

♦While most phone booths significantly reduce noise, not all products offer complete soundproofing—nor is it always necessary. In most cases, creating a private space doesn't require a fully soundproof booth. However, if you have specific requirements, opting for higher-priced products is recommended.

♦For optimal call quality, minimize reverberation inside the booth. Excessive echo makes it difficult for call recipients to hear you clearly. You can evaluate reverberation levels through on-site testing or virtual product demonstrations.
