Soundproof Room Climate Management | Ventilation, Dehumidification & Humidification Guide

“Soundproof room too hot to use…” “Instruments getting damaged by humidity…” Experiencing these frustrations?

Soundproof rooms, with high airtightness, make temperature and humidity management genuinely challenging. But proper countermeasures enable comfortable summer and winter use. This article explains soundproof room climate management basics through seasonal-specific strategies.

Why Soundproof Rooms Get Hot and Humid

#

First, understand “why soundproof rooms struggle with temperature/humidity management.”

High Airtightness Prevents Ventilation

#

Soundproof room structural characteristics complicate climate management.

Soundproof Room Structure:

• Walls, ceiling, floor completely sealed
• Minimal gaps
• Extremely limited air exchange

Meaning: Higher soundproofing performance = worse air circulation—an inherent contradiction.

Human Respiration and Body Heat Degrade Environment

#

One Person, One Hour:

• Temperature increase: +2-5°C
• Humidity increase: +10-20%
• CO₂ concentration: 2-3x increase

Longer sessions progressively worsen conditions.

Optimal Climate Ranges

#

Target Temperature

#

Summer:

• Ideal: 24-26°C
• Acceptable: 22-28°C
• Danger: 30°C+

Winter:

• Ideal: 20-22°C
• Acceptable: 18-24°C
• Uncomfortable: <16°C

Target Humidity

#

For Instruments:

• Ideal: 40-60%
• Acceptable: 35-65%
• Danger: <30% or >70%

For Humans:

• Comfortable: 40-70%
• Acceptable: 30-75%

Balance Point: 40-60% satisfies both
