- Homework Statement
- I am emulating a transmittance vs frequency plot for a research project I am apart of. However I am having difficulty understanding something. The plot has the transmittance values as a unit of decibels anywhere from 0 to -40, but the equation they’ve given me is attached below. The equation has the absolute value of the pressures so how exactly are they getting negative numbers out of this? Is there something I’m missing?

Any help would be great thank you.
