Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Type 4292-L

OmniPower Sound Source Type 4292-L is a a dodecahedral, high-power, omnidirectional loudspeaker designed to measure sound insulation and perform room acoustics measurements.

Type 4292-L

chevron_right

Type 4292-L uses 12 loudspeakers in a dodecahedral configuration to radiate sound evenly with a spherical distribution. All speakers are connected in a series-parallel network to ensure both in-phase operation and an impedance that matches the power amplifier.

The loudspeaker weighs less than 8 kg and is fitted with a convenient lifting handle that does not measurably interfere with the sound field.

USE SCENARIOS

Room and building acoustics
Measuring airborne sound insulation
Measuring reverberation time

For most architectural acoustics measurements, the OmniPower sound source radiates sound evenly in all directions and gives reproducible and reliable results. The relevant architectural acoustics measurements standards (ISO 16283, ISO 10140 and ISO 3382) require the use of an omnidirectional sound source.

Background noise is the enemy of good architectural acoustics measurements particularly at low frequencies where traffic noise and air conditioning systems are some of the main culprits i.e. between 100 Hz and 200 Hz.

The OmniPower sound source is designed to deliver its peak performance in this very same range delivering maximum power where it’s needed most.

KEY FEATURES

Part of a complete, robust building acoustics system featuring sound level meter Types 2250 or 2270
Satisfies national and international standards
Lightweight, making it easy to transport to the measurement location
Powerful, 122 dB re 1 pW, ideal for measurements in large spaces or for assessing the sound insulation of high performing walls and floors
