This slide is from a video of Rok Šturm, which classifies the study of sound communication into bioacousticians (water-borne and air-borne waves) and biotremologists (solid-surface-borne waves). Strictly speaking, both are bioacousticians in the meaning of studying communication via acoustic waves which propagate into any physical medium, but for some reasons biotremologists does not define themselves as bioacousticians.
No current questions are about solid-surface-borne bioacoustics in our SE site, so the biotremology community is not included now. Should we remain like this or expand the site area to enlarge the methodologies and to increase our chance to make this site viable in the long-term (we need many people involved)?
Traditionally regarded part of bioacoustics, the discipline [biotremology] has recently begun to actively diverge on its own, because of the many peculiarities of the studied modality compared with sound. Vibrational communication has been recognized as evolutionarily older than sound and much more prevalent, at least among arthropods, although the two modalities are closely related and sometimes overlap. While many experimental approaches are shared between the two disciplines, scientists in the field of biotremology often use special equipment, such as laser vibrometers, for detecting faint vibrational emissions by animals and electromagnetic transducers in contact with the substrate for artificial playback experiments.

Same question arises for people defining themselves as ecoacousticians / ecotrologists / soundscape ecologists
Soundscape ecology seeks a broader perspective [than bioacoustics] by considering soundscape effects on communities of living organisms, human and other, and the potential interactions between sounds in the environment. Compared to soundscape ecology, the discipline of bioacoustics tends to have a narrower interest in individual species’ physiological and behavioral mechanisms of auditory communication.

I think we should define what we call "bioacoustics" in order to explicitly include (or exclude) these other fields. If we agree to include them, we should advertise the site in their communities by saying we need them because now there are too few here.
What do you think?
