The sound field generated by tethered stingless bees (Melipona scutellaris): inferences on its potential as a recruitment mechanism inside the hive
(COMPANY OF BIOLOGISTS LTD, 2008)
In stingless bees, recruitment of hive bees to food sources involves thoracic vibrations by foragers during trophallaxis. The temporal pattern of these vibrations correlates with the sugar concentration of the collected ...
Estudo da geração de infrassom com diferentes tipos de transdutores
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de Controle e AutomaçãoUTFPR, 2017-05-22)
A characteristic of infrasound is the induction of vibratory sensation. In this study, the sound pressure level at very low frequencies necessary to produce a vibratory sensation on a person was investigated. For this, ...
