Lub anechoic chamber yog qhov chaw uas tsis muaj suab nrov. Cov phab ntsa ntawm lub anechoic chamber yuav paving nrog suab-absorbing cov ntaub ntawv uas zoo suab-absorbing zog. Yog li ntawd, yuav tsis muaj qhov cuam tshuam ntawm lub suab nthwv dej hauv chav. Lub anechoic chamber yog ib chav kuaj tshwj xeeb uas siv los ntsuas lub suab ncaj qha ntawm cov neeg hais lus, chav hais lus, lub mloog pob ntseg, thiab lwm yam.
