I’m still knee deep in propulsion sounds these days as I work on the next Rabbit Ears Audio Library. A recent recording session took me to the garage of a model jet airplane enthusiast. These planes might be small, but they pack a loud punch. Hobbyists who build these planes work with real jet turbines that are built to scale.
I performed a number of stationary runs of the turbine from several perspectives. This little turbine easily hit 115db at the exhaust, and I have no idea what kind of SPL it was outputting at the intake of the engine. IT WAS LOUD.
Here is the exhaust:
And the same take from the perspective of the air intake:
The intake has a much higher pitched whine to it, which I kind of dig. The SPL was so intense at the intake that I actually had to set that channel to line level to get useful material. I placed a DPA 4060 right in front of the intake, fed it phantom, but dropped it to line level. This can be a decent alternative to using inline pads.
I’m continuing to flesh out this collection and it continues to be ridiculous amounts of fun.
Recording Geek Note: Rig consists of Schoeps CMC5′s setup for MS, with the MK4 as the mid on the exaust and a DPA 4060 on the intake. It was all tracked to a Sound Devices 744T at 24/192.

This post comes from Stephen Vitiello who has been spending time at the Mountain Lake Biological Station in Pembroke, VA: I was tipped off to some sounds to listen for – juvenile barred owls, calling after sunset. I left a pair of DPA 4060s in a tree over night and captured some call and response and a moment of rain.

One of the things I love about long holiday weekends is that most of my neighbors head out of town. Last weekend was Memorial Day weekend here in the states, and in terms of noise, that means quiet. Not only were the neighbors quiet, but temperatures didn’t peak enough for HVAC units to start kicking on. With quiet in mind,

What is that expression about making lemons out of lemonade? Or is it lemonade out of lemons. For the next few weeks my next door neighbors are having their roof and siding redone, and if I am going to have to suffer through it, I might as well get some useful recordings out of it. This recording is from day
