For clearer streaming audio, choose absorptive panels with published performance data—around 50 mm (2 inches) thick is a useful starting point—and place them where sound from your voice reflects toward the microphone. Panels can reduce room echo; they do not soundproof a room or block outside noise. The right amount and layout depend on the room, so treat published room-design figures as guidance, not a universal panel-count formula.
What acoustic panels can—and cannot—fix
Acoustic panels absorb some sound reflections inside a room, helping speech sound less reverberant. They are useful when hard walls and other reflective surfaces make your voice sound hollow or echoey on a stream.
They are not soundproofing. Panels alone will not stop traffic, a neighbor, or household noise from entering the room, nor will they isolate your stream from other people in the home. Shure notes in its Critical Distance and Microphone Placement guidance that a microphone cannot improve the acoustic environment in which it is placed. A better mic may help capture your voice, but it cannot erase room reflections or prevent outside noise.
What to look for when choosing panels
Published absorption data
Look for a published Noise Reduction Coefficient (NRC) and, where available, frequency-band absorption data. NRC is a useful summary for comparing absorptive products, but it does not describe performance at every frequency or guarantee a particular result in your room. Google’s Room Design Guide recommends NRC of at least 0.7 for the wall-treatment context it describes.

Thickness and construction
Google’s guide identifies at least 50 mm (about 2 inches) as a wall-treatment thickness associated with achieving NRC 0.7 in its guidance. This makes 50 mm a reasonable general starting point when comparing products, not a promise that every panel of that thickness performs alike. Check the product’s actual absorption specifications; a thin decorative foam tile without performance data is a less informed choice.
Dimensions, coverage, and mounting
Compare panel dimensions with the wall area you can treat. Confirm how each panel is mounted, whether the wall can support it, and whether the attachment method suits the room. A visible finish or color may matter for a camera background, but appearance alone says nothing about acoustic performance.

Google’s guide recommends total acoustic wall treatment equal to at least 50% of room floor area plus an additional 5 m², with NRC of at least 0.7, for its room-design use case. That is a specific guide recommendation—not a universal specification for streaming rooms. A smaller room or a single-wall constraint may require a practical, targeted layout rather than that coverage figure.
Where to place panels for streaming speech
Place treatment around the strongest reflection paths near your speaking position rather than choosing locations solely for the camera frame. Google’s guide recommends treating adjacent walls and starting around seated head height. Its placement advice is a useful starting point, but the microphone’s direction, room shape, and reflective surfaces affect the best layout.

- Set up your normal speaking position. Sit or stand where you stream, with the microphone in its usual position and orientation.
- Identify nearby reflective surfaces. Pay particular attention to the walls beside you and the wall facing the microphone. Acoustic Sound Panels’ placement guide emphasizes these areas; this is vendor guidance, so adapt it to your own mic direction and room.
- Treat the most relevant reflection areas first. Put panels near seated head height on the nearby reflective wall or walls, where room reflections can reach the microphone. Google’s guide favors adjacent treated walls.
- Listen and adjust. Record a short sample from your usual position before and after treatment. If the voice still sounds reflective, reassess untreated nearby surfaces and the mic’s position before buying more panels.
If you are permitted to treat only one wall, choose based on the geometry of your setup: prioritize the reflective surface facing the microphone or the nearby wall contributing most to the audible echo. There is no single correct wall for every room and microphone orientation.
Use microphone placement with room treatment
Room treatment and mic technique work together. Shure describes critical distance as the point where direct speech and reverberant speech are equal in intensity. Moving the microphone closer to your mouth and keeping it aimed appropriately can make direct speech more prominent, but it does not remove reflections from the room. If echo remains, treat the reflective environment as well as refining mic position.

How to compare panels without relying on a shopping bundle
- Absorption evidence: Prefer published NRC or frequency-band data, and note the test context if the manufacturer provides it.
- Thickness and intended range: Use about 50 mm as a general comparison starting point, while checking the actual product specifications.
- Coverage: Match panel dimensions and quantity to the reflective surfaces you can treat; do not assume a generic bundle is right for your room.
- Placement and mounting: Check the planned wall or ceiling location, attachment method, and panel weight.
- Finish: Choose a look that works on camera after checking acoustic performance.
- Problem fit: For speech echo, prioritize nearby reflections. For outside noise or sound isolation, panels alone are not the solution.
Primacoustic’s studio brochure describes its Broadway absorption panels for streaming and podcasting. That is the manufacturer’s description, not independent comparative testing. A category search such as “2-inch acoustic panels” can help find products to evaluate, but verify each listing’s specifications rather than treating the category label as proof of performance.
Room-acoustics figures: useful context, not streaming rules
Published room targets are tied to the environments they were developed for. Cisco’s older room-acoustics guidance gives an RT60 target of 0.3–0.4 seconds for telepresence and meeting rooms. RT60 is the time for reverberation to decay by 60 dB; that target should not be treated as a universal requirement for a creator’s room. For a streaming setup, focus on whether speech is clear and whether audible reflections have been reduced.
