Hello Gianni (et al),
A number of years back I inadvertently found an interesting source of ultra-sound noise impacts on lab animals from Joanne Blum, a consultant on lab animal environments. There was a lab housing thousands of lab
rats that had an unusually high variability in their pharmaceutical testing results. When it was mapped out they found that the “unheard” variable was an ultrasonic intrusion sensor over the entryway that was screaming at all of the rats at 40kHz. The closer
the cages, the higher the variability.
There is a wealth of data on this in the Lab Animal industry. I’ll reach put
to Joanne and see if she can recommend a particular source, but you might check the lab animal literature and citations. e.g.:
https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1469-185X.1982.tb00705.x
https://www.ingentaconnect.com/content/aalas/cm/2005/00000055/00000001/art00002
https://www.sciencedirect.com/science/article/abs/pii/003193849390361I
I’ll get back with you directly if Joanne has anything more focused, but I thought I’d share this with Bioacoustics because it is a tangential, but useful intersection between our industries that might not be
obvious to all of us.

Subject: impact of ultrasounds on wildlife
Hi all,
I'm doing a review to evaluate the possible impacts of ultrasonic deterrents used in natural habitats and agricultural lands to keep wild boars away. My interest is in understanding the possible impacts on bats, however, the wide usage
of these deterrents may also have an impact on other animals, including insects and rodents.
I'd appreciate it if you can suggest literature references about studied or potential impacts, also considering theoretical approaches based on the hearing sensitivity of potential receivers.
Any hint or comment is welcome,
at present, I can't do field work because of the epidemy, and thus I have to focus on literature review for now.
with my warmest regards in this difficult period,
