About UEH LYDTEKNIKK AS
Corporate Background & Engineering Philosophy
UEH LYDTEKNIKK AS is a specialized sound engineering and architectural acoustics practice headquartered in Oslo, Norway. Established under Norwegian corporate registry (Org.nr 936 652 468, Næringskode 90.390), the organization is dedicated to advancing electroacoustic design, stage reinforcement systems, and room acoustic optimization for theatres, concert halls, performance auditoriums, and broadcast facilities.
Under the technical direction of founder Louise Steer, our engineering methodology bridges empirical physics, calibrated impulse response measurements, and digital audio network architecture to ensure flawless sonic fidelity and high speech intelligibility.
Core Mandate
To provide evidence-based acoustic analysis, high-reliability sound system engineering, and comprehensive technical documentation that empowers cultural venues, production companies, and academic institutions to achieve acoustic excellence.
Key Engineering Competencies
Our practice operates across three core domains of physical and digital audio technology:
- Architectural & Room Acoustics: Computerized ray-tracing simulations, reverberation time calibration (ISO 3382-1), sound field diffusion optimization, and low-frequency modal resonance control.
- Theatrical Electroacoustic Infrastructure: Multi-channel spatial audio routing, wireless microphone frequency coordination, Dante/AES67 digital network redundancy, and low-latency digital signal processing.
- Concert & Live Event Sound Reinforcement: Line array array-morphing calculations, cardioid subwoofer phase alignment, and noise contour modeling for environmental compliance under Nordic event standards.
Methodological Framework & Standards Compliance
Every technical consultation, acoustic audit, and system calibration executed by UEH LYDTEKNIKK AS is governed by standardized protocols:
| Protocol / Standard | Application Scope | Target Metric / Objective |
|---|---|---|
| ISO 3382-1:2009 | Performance Spaces & Concert Halls | $T_{30}$, $EDT$, $C_{80}$ Clarity Index, $G$ Sound Strength |
| IEC 60268-16 | Speech Transmission Index (STI) | STI > 0.65 in all audience zones |
| DIN 18041:2016-03 | Acoustic Quality in Rooms | Frequency-dependent tolerance curves for reverberation |
| NS 8175 (Norway) | Building Acoustics & Noise Isolation | Sound class ratings & structure-borne noise attenuation |
Laboratory & Measurement Instrumentation
Accurate acoustic modeling requires laboratory-grade calibration. UEH LYDTEKNIKK AS utilizes Class 1 sound level meters, calibrated omnidirectional dodecahedron sound sources, and multi-channel FFT acoustic measurement platforms (including dual-channel FFT transfer function analyzers and impulse response deconvolvers).
