Comparison of numerical simulation models and measured low-frequency behavior of loudspeaker enclosures

The vibroacoustic behavior of a set of prototype loudspeakers below 1 kHz was studied in
detail by comparing measurements and element model simulations. Sound fields were
measured using a microphone array of electret capsules designed for the purpose and
vibrations using a laser vibrometer and accelerometers. Simulations were carried out using
analytical, finite-and boundary-element methods, and finite-difference methods. The
enclosure conditions were varied from a fixed wall case buried in sand to a free-standing …

Comparison of numerical simulation models and measured low-frequency behavior of a loudspeaker

The vibroacoustic behavior below lkHz of a prototype closed-box loudspeaker has been
studied in detail by comparing measurements and element model simulations. Sound fields
were measured using a microphone array of 90 electret capsules and vibrations using a
laser vibrometer and accel-erometers. Simulations have been carried out using analytical,
finite and boundary element, and finite difference methods. The enclosure conditions were
varied from fixed wall case buried in sand to free-standing empty box and to free-standing …
