Measure your room's acoustic properties with professional reverberation time analysis. Room Acoustics+ calculates RT60 decay time — the standard measurement of how long sound takes to decrease by 60 dB after the source stops. Generate test impulses or clap your hands to trigger measurements. The app analyzes the decay curve in real time and provides RT60 values across multiple frequency bands, giving you a complete picture of your room's acoustic behavior. Compare your measurements against recommended RT60 values for different room types — recording studios, home theaters, lecture halls, offices, and more. Get actionable suggestions for acoustic treatment to improve your space. An essential tool for audio engineers, musicians, architects, and anyone designing or optimizing room acoustics. Understand your space before investing in acoustic treatment. ## Key features - RT60 reverberation time calculation - Real-time decay curve analysis - Multi-frequency band measurements - Comparison with recommended values - Acoustic treatment suggestions ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/room-acoustics-plus-rt60/id6760831395/reviews.md ### 1/5 — Garbage *2026-05-31* The only thing that works on this app is the ads. Apart from that nothing happens. Probably just a pocket money generator for the developer. **Developer response:** We're sorry — a microphone bug prevented measurements from working, and we've just fixed it. An update that correctly captures claps for RT60 (and reduces ads) is rolling out. We'd be grateful if you'd give it another try. ## Frequently asked questions about Room Acoustics+ RT60 ### What is Room Acoustics+ RT60 used for?
