Imagine trying to fix a car without knowing which part is making the noise. That’s what it’s like trying to solve acoustic problems without the right tools. The TSI Quest SoundPro SE 1/3 Octave RTA isn’t just another sound meter—it’s a complete listening toolkit for professionals who need answers, not just numbers.
From tracking down unwanted noise in buildings to ensuring workplace safety or evaluating how clearly your emergency systems can be heard, this device gives you detailed insight into how sound behaves in real-world environments. Whether you’re monitoring a job site, tuning HVAC systems, or performing acoustic evaluations, the SoundPro SE 1/3 turns sound into something you can see, measure, and manage with clarity.
The SoundPro SE 1/3 adapts to your workflow, no matter where or how you’re measuring. It supports multiple run modes, including scheduled start times, manual control, and external triggers, giving you full control over how data is collected.
With a rugged, lightweight design and tripod mounting capability, it’s just as effective in controlled indoor settings as it is in unpredictable field environments. Whether you’re working in a lab, a construction site, or an outdoor monitoring zone, this instrument is ready to go where the job takes you.
The SoundPro SE 1/3 integrates seamlessly with detection management software (DMS), making data management faster and more efficient. This software allows you to configure the instrument, retrieve stored measurements, and generate detailed reports with charts, tables, and exportable files.
Whether you’re conducting regulatory noise assessments or internal evaluations, DMS turns raw acoustic data into clear, professional documentation that supports confident decision-making.
The SoundPro SE 1/3 does more than measure how loud a space is, it shows you where the sound is coming from within the frequency spectrum. Using advanced third-octave band filtering, the instrument creates a live, 35-bar visual display that acts like a sound fingerprint. Each bar represents a specific range of sound frequencies, from deep rumbles to sharp, high-pitched tones. As noise occurs, the bars react in real time, helping you instantly identify which frequencies are most active.
If a certain band spikes during measurement, you know exactly where the issue lies, whether it’s a low-frequency hum from HVAC equipment or a high-pitched whine from a mechanical fault. This level of clarity turns complex acoustic data into an easy-to-read map, allowing you to target your noise control efforts with precision.
The SoundPro SE 1/3 is built for professionals who need reliable data handling in the field. It automatically records your measurements and saves them to a standard SD memory card, eliminating the need for manual tracking.
With generous storage capacity and USB connectivity, you can quickly transfer your data for review, reporting, or deeper analysis. Whether you are working on-site or back at the office, the process stays efficient and organized from start to finish.
The SoundPro SE 1/3 helps you understand noise more completely by doing the job of two meters at once. It measures different types of sound data, such as how people hear noise (A-weighted) and how machines generate it (C-weighted), all at the same time. This saves time and ensures you do not miss important details. It also gives you a real-time breakdown of the sound’s frequency content, showing exactly which parts of the noise are causing issues.
Instead of just telling you how loud it is, the SoundPro SE-2-1/3 reveals what is actually making the noise so you can fix it more effectively. Need this capability for your next project? Rent the SoundPro SE 1/3 from MFE Inspection Solutions and get the right tool without the full investment.
