SM50 Speech Intelligibility Meter - Safeguarding Perfect Sound Reinforcement Quality
Product News
The SM50 is a precise and advanced acoustic measurement instrument. With just 'one press of a button', you can measure the speech intelligibility and sound reinforcement quality of your venue. Through the intuitive color touch interface, you can easily operate and configure settings without wasting too much time reading manuals. The USB charging mode and measurement data access are fast and eco-friendly!
Just listen with your ears?
Making the construction and acceptance results of public address and sound reinforcement systems more objective and closer to the audience's needs is the ultimate goal of every integrator and system planner. However, relying solely on human hearing is not an effective way to judge, and your final test accuracy may be affected by the following factors:
● Ambient noise on-site masks the amplified content, affecting hearing
● The quality of the sound reinforcement equipment may affect the listening quality
● Obstacles or other reflective surfaces in the venue
● Human ear fatigue caused by excessive sound pressure leads to reduced speech intelligibility
● Everyone perceives sound differently, so test results tend to be subjective
Therefore, in order to quickly evaluate the key indicators after the integration of public address sound reinforcement and space, objectively reflect the quality of the sound reinforcement system in that space, and thereby achieve the goal of "clear and effective public message transmission," it is necessary to use professional instruments that adopt the internationally recognized evaluation standard (STIPA)!

What benefits can you get from the SM50?
● Before site construction: If background noise already exists around the site, you can select and purchase suitable soundproofing materials before construction, avoiding the need for re-decoration after construction and significantly reducing the required manpower and capital.
● Site Under Construction: Based on measurement results, adjust the positions of PA speakers and reflective surfaces in the venue at any time, serving as the standard for system fine-tuning and verification.
● Post-construction: Serving as the acceptance standard, ensuring users can hear every word of the broadcast clearly and providing perfect sound field quality.
Why Choose SM50?
It's that simple!
Just press a button to measure instantly! During measurement, the values are continuously updated on the instrument's touch screen, making it as easy to use as a smartphone. In addition, measurement data can be accessed via USB transmission, making it fast and convenient! A great helper for professional audio engineers.
The SM50 provides not only STI measurements but also everything professional audio and acoustic engineers need. This includes SPL testing with all common options (including A, C, and Z-weighting, Leq) and a Real-Time Analyzer (RTA) with 1/1 and 1/3 octave resolution, ensuring the most accurate and reliable speech intelligibility test results.
