Primary engineering division

Industrial acoustics and NVH—from operating symptom to verified engineering fix.

Onsite measurement, source diagnosis, simulation and mitigation for industrial machinery, environmental noise, heavy equipment cabins, HVAC systems, compressors, pumps and chillers.

The engineering question

Which source, path and operating condition controls the problem?

A single dB(A) value cannot distinguish airborne noise from structure-borne excitation, fan turbulence from a panel mode, or compressor pulsation from a mounting problem. Effective reduction begins with operating-state evidence.

KURUKONDAR connects measurement, frequency and order analysis, modal behaviour, transfer paths and simulation to a physical design change. The scope can start during concept design or with a difficult machine already operating at the customer site.

Primary business segments

Focused acoustic and vibration engineering.

These are the markets we actively position and build our specialist delivery around.

Industrial acoustic source and vibration analysis
01

Industrial Noise & Vibration

Production machinery, process equipment, structures, enclosures and rotating assets. Measurements separate tonal, broadband, impulsive, airborne and structure-borne components.

  • Sound power and sound pressure
  • FFT, order and operational deflection analysis
  • Source ranking and transfer paths
  • Enclosures, damping, isolation and silencers
Environmental industrial noise propagation analysis
02

Environmental Acoustics

Industrial noise affecting site boundaries, neighbouring buildings and communities—from baseline measurement and source inventory to propagation and mitigation.

  • Boundary and receptor measurements
  • Octave-band and tonal assessment
  • Propagation and noise mapping
  • Barrier, enclosure and silencer concepts
Heavy machinery cabin NVH engineering
03

Heavy Machinery, Tractor & Wheel-loader NVH

Cabin boom, driveline whine, hydraulic excitation, HVAC noise, speech intelligibility and whole-body vibration for long operator shifts.

  • Cabin acoustic transfer functions
  • Panel contribution and path analysis
  • Seat, floor and steering-wheel vibration
  • Mount, panel and sealing optimisation
HVAC fan, compressor, pump and chiller acoustic modelling
04

HVAC, Compressors, Pumps & Chillers

Flow noise, blade-pass tones, pressure pulsation, casing radiation, pipe-borne vibration and breakout noise across cooling and process systems.

  • Fan and duct aeroacoustics
  • Compressor and pump source characterisation
  • Mounting, piping and structural resonance
  • Silencer and acoustic enclosure engineering

Delivery scope

Measurement is the beginning—not the deliverable.

The result must identify the controlling mechanism and define a change that can be designed, manufactured and verified.

01

Onsite Measurement

Multi-channel sound, vibration, rotational speed and operating-state acquisition on machines and industrial sites.

02

Source & Path Analysis

FFT, order tracking, coherence, operational modal behaviour, TPA and contribution ranking.

03

Simulation

Structural dynamics, acoustic FEM/BEM, vibro-acoustics, CFD/CAA and propagation modelling where justified.

04

Countermeasure Design

Mounts, stiffening, damping, barriers, enclosures, silencers, duct geometry and isolation concepts.

05

Prototype & Field Verification

Before/after measurement under controlled operating conditions with traceable acceptance criteria.

06

Development Integration

Targets, test plans, design reviews and correlation loops from concept through commissioning.

Our method

Do not treat the loudest surface as the source.

The loudest panel may only be the most efficient radiator. We rank excitation sources, structural and airborne paths, modal amplification and receiver sensitivity before selecting a countermeasure.

  • 01Reproduce and instrument the operating condition
  • 02Separate source, path and radiation effects
  • 03Model only what changes the decision
  • 04Verify the engineered change on the machine or site

Published application cases

Technical problems from heavy machinery and industrial cooling.

Published engineering analyses based on field experience; confidential customer identities and data are excluded.

Heavy machinery

Tractor NVH is an endurance problem, not only a decibel target.

Low-frequency boom, driveline excitation and soil-induced vibration across 14–16 hour shifts.

Before we start

Scope and evidence.

Can you measure onsite?+

Yes. The measurement plan is matched to the operating condition, frequency range, channels, reference signals and decision the data must support.

Do you cover environmental and industrial noise?+

Yes. We support source inventories, site and boundary measurements, octave-band and tonal assessment, propagation analysis and mitigation concepts. Formal regulatory sign-off is agreed separately where accredited measurements are required.

Can you work on compressors, pumps and chillers?+

Yes. The diagnosis can combine acoustic, vibration, rotational and process data to separate mechanical excitation, pressure pulsation, flow noise, structural resonance and mounting or piping paths.

Do you design the countermeasure?+

Yes. Depending on the root cause, this may include geometry changes, stiffening, isolation, damping, enclosures, barriers, silencers or operating-control recommendations.

Acoustics & NVH project

What is heard, felt or measured—and under which operating condition?

Send the symptom, spectra or recordings, machine information and operating states. We will define the evidence needed before proposing a fix.
