Dodec Model Comparisons 

Dodecahedron (Dodec) speakers provide omnidirectional sound that allows for clear testing of building acoustics and sound insulation. The sources of all 3 Dodecs can be driven from a sound level meter or an internal noise source that has been equalised for a flat response over the complete frequency range.

Is your Dodec or Cabinet speaker meeting the tough SITMA standards for directivity and stability checks?

If not, then take a look at our Dodecs, that will fly through the tests and come with a pretest certificate. Tested in our state of the art calibration facility.

About the Dodecs

Thanks to careful design, Lookline has placed all the electronic circuits inside the spherical sound sources, making these instruments extremely compact. Within these dodec’s you will find twelve loudspeakers, a digital amplifier and an advanced generator. This maximises the practicality and makes it perfect for conducting measurements in various locations. Operating the omnidirectional sound source is straightforward; it is available in two options one with mains voltage or with a battery.

 SITMA Compliance

Our dodecs meet the following requirements for SITMA Speaker Stability and Directivity checks.

Speaker Stability Check

All testers must conduct a speaker stability check with each of their speakers at least every 2 years. This is to ensure the output level of the speaker does not change during the test, which would impact the overall result.

Speaker Directivity Check

BS EN ISO 140-4:1998 requires speaker directivity to be checked as part of Annex A. This is a mandatory requirement of the SITMA Certification Scheme and must be completed and recorded onto the SITMA Portal annually.
Speaker Directivity can be checked either by the certified tester, or at a facility that offers this service
