Clients specify SPL and frequency response coverage as the primary metrics for audio system design, but neither tells you whether speech will be understood by the people in the room. Speech Transmission Index measures something fundamentally different, the preservation of modulation through the transmission channel, and by the time poor intelligibility surfaces after installation, the problem is almost never in the electronics.
High STI is not the result of powerful amplifiers or expensive loudspeakers, it is the result of disciplined system design that treats the room as part of the signal chain. This article documents the engineering methodology across four of the most acoustically demanding venue categories: churches, mosques, government buildings, and airports.
Smaart, the NTI XL2, and the NTI TalkBox each occupy a distinct role in the measurement chain, and confusing those roles is one of the most common sources of error in installed audio commissioning. This article breaks down what each tool actually does, why coherence is the most misread trace in Smaart, and why a single-point STI measurement should never close a project.
Stage monitors exist for one reason: performer confidence. But the tool you choose to deliver that confidence shapes the acoustics of the entire show.
Low-frequency sound is omnidirectional by nature. How you position your subwoofers is the single most powerful tool you have for shaping the reverberant field.
A DSP processor is not a magic box. Every parameter you set has a physical consequence. Understanding each processing block is the difference between a great-sounding system and a loud one.
The choice between a two-way and three-way loudspeaker system is rarely made with full understanding of what each driver is physically being asked to do, where the crossover points fall in the spectrum, and what happens in the transition between drivers when the engineering is not rigorous. This article examines the mechanics, the tradeoffs, and the conditions under which each architecture is the right answer.
Late-night system tuning before a big show.
