to their production of soft songs. In the Asian corn borer moth, Ostrinia furnacalis, males produce an ultrasonic soft song to initiate courtship behaviour. The song that the male produces is so quiet that the female must be within a range of three centimeters in order to hear the song. In hearing the song, the female stays in one place and is completely still; this allows the male to initiate mating behaviour. The reason that the female remains still is because the song sounds very similar to sounds that a bat would produce. The female therefore remains still in order to avoid potential predation. There is another added benefit to this soft song produced by the male Asian corn borer moth, and that is that the song is so quiet that it decreases the males’ predation risk. Although these soft songs are far less well known to the general public, they are an important aspect of zoomusicology and the further understanding of animal behaviour. Auditory enrichment and therapeutic effects of music on animals Cows In an unpublished study at the University of Leicester, Liam MacKenzie and Adrian North found that playing music for dairy cows had an effect on the amount of milk that they produced. Over a nine-week period, dairy cows were exposed to fast (> 120 BPM), slow (< 100 BPM), and no music. Music was played for the cows 12 hours a day from 5 AM to 5 PM. The study found that cows exposed to slow music, like REM's 'Everybody Hurts' or Beethoven's 'Pastoral Symphony,' produced 3% more milk than cows that were exposed to fast music, like Pumping on your Stereo by Supergrass and 'Size of a Cow' by Wonderstuff. Bovine milk production has long been thought to be affected by exposure to music. Some farmers already expose their cows to music to aid in milk production. Dogs Decreased stress levels have been observed in kennelled dogs that were exposed to classical music, but rapid habituation was also observed. In a 2017 follow up study, kennelled dogs were exposed to five different genres of music including soft rock, Motown, pop, reggae, and classical in order to determine whether or not increased variety of music could reduce habituation. The study found the Heart Rate Variability, which indicates a decreased stress level, was significantly higher when the dogs were played reggae and soft rock, but the other
