This is the sound that myself and others agree is what you hear when a loud noise makes your ears ring. Why this particular frequency? i don't know. It's just a simple generated tone--you can loop it to make it longer.
Generate a sinusoid at 150hz and a whistle repeat once which is inverted. Modification of the envelope to create a fade in and fade out. Between the 2 whistle, modification to have no jump. Then generate a tone and placed it like the gradation with the whistle.
This is some room tone i recorded in a thankfully quiet time in my studio. It's an oktava 012 microphone in our whisperroom with the door wide open. Signal path is a neve 1272 and an apogee mini-me. Recorded in 24-bit at 48khz.
