Noting that the researchers use terms as 'responds to vibroacoustic signals' rather than the term 'hear' used in the article of the post. Hearing to me implies some kind of auditory processing, this seems to be a more passive 'biomechanical' response.
The study is ongoing, the researcher presented their findings so far at a conference. Here's an article: https://phys.org/news/2025-05-nectar-production-response-pol... and a link to the study abstract: https://www.hfsp.org/node/74710
