Summary: It is not uncommon to find amateur music rehearsal rooms covered with egg boxes as it is an economical solution to allegedly improve the acoustics. This research characterizes acoustically the use of alveolar containers for storage and transportation of food supplies. Eight distinct types of boxes for eggs and trays for fruit were analyzed, in a total of 21 different arrangements and materials. The results of sound absorption coefficients (S) measured in a reverberant chamber are presented and discussed. In summary, NRC values between 0.20 and 0.70 were obtained.
