| Longitudinal pressure waves having frequencies
between 20Hz and 20,000 Hz are sensed by the human ear. The
name given to these waves is 'sound' or 'noise'. Design engineers
sometimes want to reduce noise and sometimes need to produce
sound. We at Mechartés assist engineers in understanding
the sound sources and propagation of sound in any medium.
Noise reduction
In order to reduce the sound that is generated from machinery,
we first measure the sound generated, then conduct Fourier
transform of the sound pressure wave to determine the sound
characteristic. The sound created is simulated using FEM,
CFD and analytical Tools.
Automobile horn consultancy
Mechartés has rich experience in designing & analyzing
automobile horns. We have also developed a software tool (Résorn)
to predict sound produced from a horn. We use our experience,
Résorn & analytical skills to help horn companies
develop new products and solve quality related problems in
existing horns.
Structural Acoustics
Under this, we conduct analysis of convention centers, halls,
theaters etc for their acoustic design and determine how sound
waves of different frequencies travel in the room.
