Abstract
I read with interest the article “The sounds around us” by Megan McKenna (Physics Today, January 2020, page 28). I wonder if anyone is studying the sounds of animals communicating while they are confined in slaughterhouses or in trucks transporting them to slaughterhouses. Are those sounds different from the ones they make as they join the assembly line during slaughter? And does anyone study the sound of a dairy cow as its newborn calf is taken away? She must communicate a lot.My take is that communication among nonhuman animals is of no concern to humans when it comes to their taste buds or their pocketbooks.
