Voltas Limited AC-Plant – Rudrapur
Case Study: Voltas Limited AC-Plant – Rudrapur
Acoustic Solutions for Manufacturing Environments by MMTPL
Project Overview
Client
Voltas Limited (Tata Enterprise)
Location
Rudrapur, India
Scope
Noise reduction in manufacturing plant
Total Area Covered
600 m²
Objective
Minimize industrial machinery noise in the AC manufacturing facility and enhance the acoustic environment for operational efficiency and worker comfort.
Acoustic Challenges
1
High-Noise Machinery: HVAC and compressor equipment producing continuous airborne noise impacting plant operations.
2
Echo & Reverberation: Hard reflective surfaces within the plant amplified noise levels.
3
Compliance Requirement: Reduce noise exposure to meet industrial health and safety standards (< 85 dB).
Solutions Implemented by MMTPL
Pyramid Acoustic Foam Panels
Specification: NRC 0.90
Design: 2" Pyramid profile for effective mid-high frequency absorption.
Application: Wall and ceiling treatment across noisy production areas.
Function: Reduced internal echo and reverberation, improving sound clarity and lowering overall noise levels.
SoundBlanket® MLV (6 mm)
Performance: STC 34 – Effective airborne noise blocking barrier.
Application: Installed on partition walls adjacent to offices and quieter plant zones.
Function: Created a dense acoustic barrier to isolate noisy zones within the plant.
Execution Scale
Total Area Treated
600 m², combining absorption (pyramid foam) and isolation (MLV 6 mm).
Zones Covered
Production floor walls
Adjacent partitions near administrative spaces.
Results
Noise Reduction
Significant drop in internal reverberation time (RT60).
Airborne noise blocked between plant floor and adjoining workspaces.
Acoustic Performance
Composite performance achieved STC 50+ walls and NRC-controlled interior acoustics.
Worker Comfort
Improved speech clarity, reduced noise fatigue, and compliance with OSHA industrial standards.
