ACOUSTICAL ENGINEERING

Acoustics is the branch of engineering related to auditory sense and speech. Noise pollution is attributed to injuries, discomfort and fatigue in human and is a growing concern. High  quality sound without noise is desirable.  Acoustical design principles are used in Architectural Acoustics, Automobile NVH, Environmental Noise control, structural dynamics, underwater acoustics, audio devices, ultrasonics and hypersonics.  Miniaturization, Noise cancellation, acoustical metamaterials are the growth trend. ATOA provides all aspects of sound engineering simulations for minimizing noise pollution and improving the performance of acoustical products.

Acoustical Engineering Simulations Solutions

Sound wave propagation and its interaction are critical to predict the performance and to minimize the noise level and enhance the quality of sound. We provide simulation services spanning all aspects of acoustical engineering simulations in both frequency and time domain for, Virtual sound measurement, sound reduction, Soundproofing, Noise reduction and Noise Control. We provide following basic acoustical Engineering simulations,

Emerging Acoustical Engineering

Our focus on emerging technologies related to Acoustical Engineering are,

  • Acoustic metamaterials, Sonic or Acoustic crystals for novel soundproofing, focussing, concentration and acoustic wave guiding.

  • Miniaturisation of acoustical system for use in mobile electronic devices.

  • Multilevel acoustical modelling for broadband response and near zero sound absorption.

  • Passive noise cancellation panels.

ATOA’s  New addition to  Acoustical Engineering Solutions,

  • 3D Printing of Acoustical metamaterial based products.

  • Acoustical Engineering design apps for sound transmission loss, STL, resonance, transmission, reflection and absorption prediction.

Acoustical Engineering spans a wide application area from architectural to automobile to industrial to consumer to defence. Wave equation for sound waves governs the compressible lossless fluid flow problems. For the special case of time-harmonic, wave equation for acoustic wave propagation reduces to an inhomogeneous Helmholtz equation.  Wave equation coupled with Navier-Stokes equation is used for solving Coupled Acoustical and flow problems such as aero and thermo acoustics. Multiphysics CAE and Acoustical metamaterials takes acoustical engineering to a new height for innovative  noise handling solutions.
