Noise levels, ICU 11/2022

I have 7 days of data with 43,200 points of data for each day. I already have these days in individual excel spreadsheets and I need to create graphs, one per each day. I will need the x to be time of day and y to be the number of decibels the device recorded. I am ok with sorting/averaging/taking the high number of decibels per minute or per 5 minutes if needed. This does not need to be perfect, just a rough visual. Ultimately refinement of the recording process and project development will take place, so future work with more detail is possible.
