Project Main Details

Basics of Acoustics 
I will provide a powerpoint presentation (17 slides) about basic acoustic topics. We want the notes to be recorded in an enthousiastic but professional (swift and to-the-point) way. It will serve for new engineers or engineer-like people to repeat these basics. At this point we have about 250 engineers working world-wide.

This means that the type of text is like the text in the audition box and the voice actor should feel comfortable doing this.

For a price indication: This is the text of one slide so the total text is about 17 times this text...

Script Details

We want the notes to be recorded in an enthousiastic but professional (swift and to-the-point) way. 
Sound is typically measured via the instantaneous sound pressure fluctuations and is annotated with the unit “Pascal”.

Those pressure fluctuations are variations on top of the static atmospheric pressure that surrounds us.
The magnitude of these pressure fluctuations falls in the range of 20 micro Pascal up to 10 or 20 Pascal.
This is very small compared to the atmospheric pressure of 100 kilo Pascal.
You can understand that we need a very sensitive device to measure these fluctuations.

Luckily, our brain does not respond to the static atmospheric pressure nor to the instantaneous pressure fluctuations.
Our ear is behaving like an integrator, averaging and smoothing out the pressure fluctuations over a certain time period.

[link to formula]
This is mathematically expressed as an RMS or root mean square average.
This averaging results in a single number, which we call the sound pressure level. 
Please note that you should only use the script or your recording of it for auditioning purposes. The script is property, unless otherwise specified, of the voice seeker and it is protected by international copyright laws.
