[TriEmbed] Monitoring Environmental Sound

[Rob Parsons]

Hi All,

A project...

I have been interested in monitoring environmental sounds for quite a long
time.

Am I hearing "The Hum"?

My wife does not hear it.

What is driving my dog crazy sometimes?
(Dog hearing range is 40Hz - 60000Hz)

What hidden sounds is my house generating?

There are some ultrasonic microphones.

Some are very expensive.

My 'Analog Discovery 2' has a spectrum analyzer feature. Been looking for a
microphone or ultrasonic sensor that I could hook up to it.

Anyone out there done any work in this area?

Rob
