This is my recording of a antique/vintage 1920's-1940's telephone picking up and hanging up. Recorded at the military aviation museum in 1341 princess anne rd, virginia beach, va 23457 during the summer of 2021.
I created a dtmf tone with an amplitude of 0. 8 and a tone/silence ratio of 550 and during 7s. Then i amplified 1. 3 db sound. And finally i multiplied the speed of 0,960.
To create this sound, i created a sinusoid of 500 hz and an amplitude of 0. 8. I then multiplied the speed of 0. 750. To get this final sound is to duplicate the sinusoid several times.
An edited version of my "boiling water" sound to simulate a phone vibrating on a table. Recorded for my sound design class using a samsung galaxy s7 internal microphone.
