In the fields of electroacoustic product research, subjective sound quality evaluation, voice algorithm debugging and architectural acoustic simulation, traditional fixed-parameter listening rooms can hardly meet diversified industrial testing requirements. Conventional listening rooms adopt fixed sound absorption and diffusion structures with unchangeable indoor reverberation parameters, only supporting basic sound inspection work. However, actual user scenarios vary greatly in daily application, including small residential spaces, open meeting rooms, spacious halls and noisy outdoor environments. The single sound field of traditional laboratories often leads to inconsistent performance between laboratory test results and real-scene usage. Many audio products perform well in fixed laboratory environments but suffer from sound imbalance, voice recognition failure and poor listening experience in actual application. Enterprises that rely on multiple independent listening rooms or on-site outdoor testing face high site costs, low equipment utilization and unstable test repeatability, restricting product iteration efficiency and evaluation credibility.

Our custom adjustable reverberation listening room is a multi-functional variable sound field laboratory tailored for diverse acoustic testing demands, solving the functional limitations of traditional fixed acoustic spaces. Designed in compliance with local industrial acoustic specifications and international ISO acoustic evaluation standards, the room is equipped with intelligent adjustable acoustic systems, including electric reversible sound absorption panels, liftable sound-absorbing structures and controllable diffusion modules. Supported by a central control system, it flexibly adjusts the indoor ratio of sound absorption and sound reflection, realizing continuous reverberation time adjustment and covering short-reverberation dry sound fields, medium-reverberation balanced sound fields and long-reverberation immersive sound fields. The enclosed sound insulation structure and basic vibration isolation design isolate external ambient noise and structural vibration interference, maintaining a pure and stable acoustic environment and ensuring consistent testing conditions during sound field switching and acoustic evaluation.

With flexible and variable sound field performance, the listening room adapts to a full range of audio and acoustic application scenarios. In consumer electroacoustics, it supports subjective sound quality evaluation and objective parameter debugging for earphones, Bluetooth speakers, vehicle-mounted audio and home audio-visual equipment. By switching different reverberation parameters, it simulates daily usage scenarios such as living rooms, bedrooms, car cabins and mini audio-visual rooms, helping R&D teams eliminate sound defects including human voice distortion and low-frequency turbidity, optimize product acoustic structures and adjust audio parameters. This effectively bridges the gap between laboratory testing and real-scene usage, improving product adaptability for diverse living environments.

In the field of intelligent voice technology, the matched adjustable background noise system cooperates with variable reverberation to simulate complex environments such as meeting rooms, open exhibition halls and noisy indoor spaces, supporting algorithm calibration and performance testing for voice recognition devices, intelligent sound pickup sensors and call noise reduction equipment. For architectural acoustic research and music creation, the room simulates the sound field characteristics of churches, auditoriums, exhibition halls and offices, verifying the practical effect of sound absorption materials and architectural acoustic design schemes, and supporting post-production debugging for film and television audio works. For university laboratories and SAC-accredited testing institutions, the adjustable reverberation listening room enriches acoustic testing and research categories, covering product evaluation, scene simulation and algorithm research with a single space, reducing site construction and operation costs.

We deliver fully customized solutions based on actual site size, floor height, mainstream testing categories, conventional reverberation ranges and daily usage frequency. The integrated solution includes intelligent acoustic adjustment systems, sound insulation enclosure structures, noise reduction ventilation systems and central control terminals. After installation, multi-gear sound field calibration, reverberation parameter verification and ambient noise testing are completed to ensure stable sound field switching and standard-compliant parameters. Long-term after-sales services including equipment maintenance, sound field calibration and technical support are provided, delivering sustainable and reliable variable sound field support for product R&D, acoustic evaluation and academic research for enterprises and institutions in Singapore and Southeast Asia.
