About SCEAIMS

Professional Acoustic Solutions

Measurement · Analysis · Treatment · Validation

SCEAIMS CINEMA is a specialist acoustic engineering firm headquartered in Salem, Tamil Nadu. We deliver end-to-end acoustic treatment for a wide spectrum of spaces — from multipurpose auditoriums and home cinemas to corporate boardrooms, executive cabins, podcast studios and professional recording spaces. Every project begins with calibrated measurement, is guided by scientific analysis, and concludes with independent before-and-after validation — ensuring the result is not an estimate, but a proven outcome.

RT60 Target Standards by Application

Reverberation Time · ISO 3382 Compliant Measurement

RT60 (reverberation time to 60 dB decay) is the primary metric governing acoustic quality. SCEAIMS measures RT60 across low (125–250 Hz), mid (500–1000 Hz) and high (2k–4k Hz) frequency bands and designs treatment to meet the target range for each specific room application.

Application Type	Target RT60 (Mid)	Low Freq Target	High Freq Target	Primary Challenge
Speech Auditorium	0.7 – 1.2 s	0.8 – 1.4 s	0.6 – 1.0 s	Clarity & intelligibility
Conference Hall	0.6 – 1.0 s	0.7 – 1.2 s	0.5 – 0.9 s	Noise & HVAC isolation
Multipurpose Hall	1.0 – 1.8 s	1.2 – 2.0 s	0.9 – 1.5 s	Variable use flexibility
Music Auditorium	1.8 – 2.2 s	2.0 – 2.5 s	1.5 – 2.0 s	Warmth & envelopment
Home Cinema	0.3 – 0.5 s	0.4 – 0.6 s	0.2 – 0.4 s	Reflection & flutter
Boardroom	0.5 – 0.8 s	0.6 – 1.0 s	0.4 – 0.7 s	Echo & reverb tail
MD / Executive Cabin	0.4 – 0.7 s	0.5 – 0.8 s	0.3 – 0.6 s	Privacy & isolation
Podcast / Broadcast	0.2 – 0.4 s	0.3 – 0.5 s	0.2 – 0.3 s	Dead room uniformity

Room-Specific Solutions

Home Cinema

Thick broadband absorption on all parallel walls, ceiling cloud panels, bass traps in corners, isolated floating floor and door seals to eliminate vibration leakage and create an immersive experience.

Podcast & Broadcast Studio

High-density absorption panels, movable gobos, low-noise ventilation ducting, and a vocal-booth design achieving a near-dead acoustic field suited for spoken-word recording.

Boardroom & Conference

Fabric-wrapped wall panels targeting mid-frequency intelligibility, suspended ceiling clouds, HVAC noise attenuation, and triple-glazed acoustic partitions for privacy.

Professional Recording Studio

Multi-shell construction, floating floor systems, room-within-room isolation, QRD diffusers in the live end, and custom corner bass traps achieving NR20 noise criteria.

MD / Executive Cabin

Decorative acoustic solutions integrating absorption into premium fabric finishes and wood veneers; acoustic doors and sealed penetrations for speech confidentiality.

Multipurpose Auditorium

Variable absorption systems using motorised banners or movable panels, enabling RT60 adjustment between speech (1.0 s) and light-music (1.6 s) configurations.

Before & After: Measured Results

RT60 Reduction — Independently Measured & Documented

Case Study — 2025

Kongu SRV International School — Multipurpose Hall

Salem, Tamil Nadu | Pre-Treatment: 25 July 2025 | Post-Treatment: 04 September 2025

The Kongu SRV International School multipurpose hall is a large, hard-surfaced room used for school assemblies, examinations, cultural programmes and guest lectures. The initial acoustic condition was characterised by extreme mid-frequency reverberation — as high as 8.0 seconds — making speech virtually unintelligible and background noise overwhelming. SCEAIMS was commissioned to deliver a treatment achieving a mid-frequency RT60 of 1.5–2.2 seconds.

Our Differentiators

Why Choose SCEAIMS

◎

Measurement-Driven Approach

Every project starts with calibrated RT60 measurement — not assumptions. Targets are set to ISO 3382 standards and validated after treatment.

◈

Application-Specific Design

We design to the room's actual use — a speech auditorium needs a different acoustic profile than a home cinema or recording studio. One specification never fits all.

△

Technical Engineering Rigour

Room-mode analysis, material NRC ratings, mass law calculations and STC verification are part of our standard design process — not optional extras.

◇

Integrated AV & Acoustic Design

Acoustic design is coordinated with AV speaker placement, screen geometry and lighting — ensuring every system reinforces the others rather than competing.

▣

Independent Before & After Validation

Measurement reports are provided at both pre-treatment and post-treatment stages — giving clients an independent, auditable record of performance improvement.

✦

Complete Turnkey Solution

From site survey and acoustic design through material supply, installation and final commissioning — SCEAIMS manages the full project scope under one contract.

Our Promise
