Bioacoustics
• Animals can be elusive
– In particular birds, bats, insects
• Better detected by their sound
• Better classified by their sound (speciation)
Example
• iBats – Bat mobile

The New Forest Cicada
• Native to the UK
• Only in the New Forest
• Call at ~13.5 kHz
• Most people >40 can’t hear it
• Those who can, hear it even
60m away
