Content & Technical Disclaimer

Effective Date: September 2026 Entity: UEH LYDTEKNIKK AS Jurisdiction: Oslo, Norway

1. General Engineering & Educational Information

The technical articles, calculation algorithms (including reverberation time estimators and SPL formulas), whitepapers, and operational guides published across this domain are intended to serve as educational and preliminary engineering references. While every effort is made to reflect empirical acoustic physics and standardized European engineering criteria (such as ISO 3382, IEC 60268, and DIN 18041), website calculations are simplified numerical approximations.

2. Requirement for Certified On-Site Verification

No online calculator, digital monograph, or automated parameter tool constitutes a substitute for an on-site structural acoustic inspection and calibrated measurement executed by qualified acoustic engineers. Physical venue characteristics—such as structural resonance, mechanical HVAC noise, temperature gradients, and non-uniform boundary absorption—require individualized measurement with calibrated Class 1 sound level meters and calibrated acoustic sources.

3. Sound Pressure Levels & Hearing Protection

UEH LYDTEKNIKK AS strongly advocates for audience and production crew hearing conservation. System operators and event managers are solely responsible for ensuring that live sound pressure levels remain within permissible occupational and municipal thresholds as specified by Norwegian environmental health regulations ($L_{Aeq, 15\text{min}} \le 100\text{ dBA}$).

4. Limitation of Technical Liability

Under no circumstances shall UEH LYDTEKNIKK AS, its directors, or engineering personnel be held liable for direct, indirect, incidental, or consequential damages resulting from the implementation of general online guidance, improper hardware rigging, or unauthorized electrical modifications made without formal written engineering commissioning.

5. Contact for Formal Acoustic Auditing
