Abstract
The new validation-step we are proposing simulates an open-field environment by setting up an electro-acoustic chain in individual small anechoic boxes, isolating every node from one another. Two different designs are being presented: the first ABox has modular pieces making it easier to build; the second and improved ABox design is more complex due to the application of advanced room acoustics theory. Both boxes were built using materials and components that can easily be obtained in a standard hardware store. With this method, basic testing of an acoustic wireless sensor network is possible and future work could expand the field of application of this validation step. For example, ABox could be further developed to allow testing of microphone array sensor networks. ABox also provides opportunities for the development of methods to characterize anechoic environments.
