Cicada orni Air emission- Vs - Ground reflection by Marco Pesente published on 2021-07-06T16:09:47Z This morning I recorded a Cicada orni with Hi Sound Evo 4 AOM capsules parabolic microphone. The insect was at about 20 meters far from me at an height of about 10 meters from the ground on a chestnut tree. Pointing down the dish towards the asfalt surface I noticed the reflection of the sound wave emitted by the cicada. Then I recorded in this position, with the dish pointed pointed to a meter from me, down to to the ground at about 90 degree related to the sound source. The maximum energy of the sound was at about 5000 Hz. This is a section of the file, at the beginning pointing directly towards the subject and later pointed down as previously described. Yesterday I had the same experience with another smaller specie of cicada the Dimissalma dimissa, with a maximum energy at a frequency around 14000 Hz. In this case too I obtained the recording pointing the dish directly to the ground, towards the reflected wave. Genre test parabolic microphone
