Fletcher Munson EQ

Using an dB meter app in my phone and a professional dB meter I measured that the projector in our class is around 58-59dB.

What?

What activities have I completed this week?

We learnt about different weighting for measuring dbSPL and had a look and used some measuring equipment.

So What?

So, what have I learned this week?

how to use a dbSPL measuring tool and what the Fletcher Munson EQ represents.

Am I on the right track with this unit?

Yes I think so.

Now What?

Now what will I do to move forward?

I need to work on project 1.

What feedback did I receive this week?

Add notes below from any feedback provided in class, during activities or as part of tasks.

The dbSPL app I found can be used for the project in conjunction to the proper tool.
