Measuring BT speaker for university assignment

[amazingstriker4]

I need to measure frequency response, THD, noise floor, dynamic range and dispersion. I already know how to measure frequency response in REW even though the reading is a bit flat and i maybe screwed up somewhere. Can someone tell me in detail how to measure each parameter? Thank you!

Post this somewhere else and maybe you’ll get a response. Did you read the sticky before posting here??

Moved to REW Forum.

I don't know that REW can measure dynamic range or dispersion. Hopefully others will weigh in to help with the rest.

Regards,
Wayne

focus your delay time and time windows

Every sweep measurement also captures distortion, just look on the Distortion graph. To measure polar response this thread may help: https://www.audiosciencereview.com/...ents-spinoramas-with-rew-and-vituixcad.21860/

Noise floor and dynamic range are more relevant for electronic devices than acoustic, there are few acoustic environments quiet enough to measure noise floor outside of anechoic chambers. Maximum SPL can be measured using shaped tone bursts, the methods are set out in CTA-2034 which is available as a free download from the CTA website https://shop.cta.tech/collections/s...ethod-of-measurement-for-in-home-loudspeakers
