Live Sound Toolkit Terms of Use

Effective: November 1, 2026

Safety

• Loud sound causes permanent hearing loss. Wear hearing protection at shows and keep exposure within the limits in Noise Exposure.
• Phone microphones are not calibrated instruments. SPL readings are estimates and cannot be used for compliance or legal limits.
• Start test tones and noise at a low level with faders down. Sweeps and square waves at high level can damage drivers and hearing.
• Mains power distribution must be planned and connected by qualified people to local electrical code. The power tools give estimates only.
• Check voltage, earth and polarity before connecting equipment. Never remove or defeat a safety earth.
• Flying, stacking and rigging speakers are not covered by this app. Follow the maker's instructions and the venue's rules.
