Industrial Silencers
Product Overview
SISCO Energy (formerly Acoustics India) has been engineering industrial silencers for over 38 years, delivering noise attenuation solutions across Oil & Gas, Power Generation, Defence, Aerospace, Mining and Transit infrastructure worldwide.
Design Technologies
Four Type of Silencer
SISCO selects and combines the optimal silencer design technology based on your noise spectrum, process gas, pressure and flow requirements.
01
Absorptive
Incorporates sound-damping materials (mineral wool, acoustic fill) within lined baffles or annular passages to absorb broadband noise energy from flowing gas or air. Highly effective across mid-to-high frequency ranges.
02
Reactive
Uses precisely dimensioned expansion chambers and resonator cavities to reflect and cancel acoustic energy at specific frequencies. Ideal for tonal noise, compressor pulsations and low-frequency dominated spectra without absorptive media.
03
Tuned Dissipative
Constructs precisely tuned cavities based on the Helmholtz Resonator principle to attenuate discrete frequency components. Provides exceptional insertion loss at targeted frequencies with minimal pressure drop — common in gas turbine intake systems.
04
Hybrid
Combines absorptive and reactive design elements into a single unit to address complex broadband-plus-tonal noise spectra. Engineered for high attenuation across the full audible range — typical in vent silencers, engine exhausts and wind tunnel systems.
