What the NC curves mean, target levels by space type – offices, hospitals, concert halls, classrooms, industrial – and how HVAC equipment and duct silencers drive whether a room actually hits its number.

Acoustic panels, diffusers, and bass traps all get sold as ‘sound treatment’—but they solve different problems at different frequencies. Here’s what each one actually does, when to use it, and how to combine them.

How long a room “rings” after sound stops – RT60 targets from 0.2-second recording booths to 3-second cathedrals, the Sabine formula behind them, and treatment strategies for each frequency band and room use.

OITC measures how well exterior walls and windows block outdoor noise – traffic, aircraft, trains. A full reference: typical assembly ratings, recommended targets by site, and why OITC numbers run 5-10 points below STC.

How sound waves move through tissue and bone, not just the ear – what low frequencies do to circulation, the nervous system, and cortisol, and why dose, duration, and vibration exposure matter more than volume alone.

STC rates indoor speech and TV; OITC rates outdoor traffic, trains, and aircraft. Why OITC is always lower on the same assembly, where each rating belongs, and the spec mistake behind most low-frequency complaints.

The ceiling is usually the largest reflective surface in a room. How ACT systems absorb, block, or diffuse sound, the three main material types, and where they actually deliver acoustic comfort versus just aesthetics.
