How Are Esports Commentary Booths Designed for Live Casters?

The booth envelope is designed from the crowd inward. The engineer sets the composite STC target from the measured or modeled bowl sound level at the booth location — booths closer to the crowd or the PA need more isolation — and specifies the wall assembly, typically double-stud or staggered-stud with multiple drywall layers, to meet it. The bowl-facing window gets laminated acoustic glazing in an isolated frame, with the two leaves at different thicknesses to avoid coincident resonance; the engineer details the frame seals as carefully as the glass, since a leaking frame defeats expensive glazing. Flanking paths get the same attention as the envelope. The booth's ductwork connects through silencers and flexible connectors so it never becomes a sound conduit to the adjacent spaces; the cable penetrations for talkback, monitors, and power are sealed with acoustic putty or packed and caulked; and the door — the most-used element — gets perimeter seals and a drop seal rated for daily cycling. The engineer walks the completed booth with the acoustician's punch list before the broadcast ever tests it, because seal failures are found by inspection, not by calculation.

The ventilation design treats silence as the load. The engineer calculates the booth's sensible heat — casters, monitors, broadcast lighting — and selects a supply rate that holds temperature with air moving slowly enough to stay inaudible, which usually means a dedicated branch with an oversized silencer rather than a tap off a larger duct. Return air gets the same silencer treatment; an untreated return grille is a direct sound path to the corridor. The controls are local and simple: a quiet thermostat the casters can reach without standing up. At the desk, the engineer lands everything the broadcast needs: isolated-ground technical power, talkback panels tied to the production intercom, monitor feeds for program and preview, and a hardwired connection for the casters' statistic and notes systems. The lighting design gives the booth camera a properly lit shot — soft key light at the right color temperature, fill to kill harsh shadows, all flicker-free and dimmable — while keeping every fixture out of the casters' monitor sightlines. The booth's position is finalized with the broadcast director: sightline to the stage for the casters, sightline to the booth for the camera, and no house-PA loudspeaker aimed at the booth window.

Use this checklist when the commentary booth design is set: • Composite STC 50 or better envelope, targeted from the actual bowl sound level at the booth location • Laminated acoustic glazing in isolated frames; different glass thicknesses to avoid coincident resonance • Sealed doors with perimeter gasketing and drop seals rated for daily cycling • Dedicated low-velocity ventilation with silencers on supply and return; NC-20 or better at caster positions • Local thermostat reachable from the desk; diffusers selected for lowest noise at design flow • Technical power, talkback, IFB, and program and preview monitor feeds at the desk; UPS-backed • Flicker-free dimmable camera lighting on the casters; no glare on monitors, no fixtures in sightlines • Booth position coordinated with the broadcast camera plan: casters see the stage, camera sees the casters
