Lessons from the past internship!

Hi everybody! I haven’t written in a while because I was in Francfort last weekend! This week, I want to talk about something that I did that is directly related to what I did during my internship this summer!

For those who are not familiar with this blog, my ultimate goal last year was to find an internship in the US. I found one in California and I was mainly working on room acoustics projects. My work consisted in estimating and reducing the reverberation time, the dime during wich the sound decreases by 60dB. And this week, I was selected to do a similar mission in France!

The client was a Carmelite monastery that has a conference room with a very long reverberation time: close to 2 seconds! Our job on Wednesday was to go there and take measurements of sound decay and of the room dimensions as well. The next step will be to model the room on computer and to see if the reverberation time that we compute is the same than the one that has been measured. Then, we will be able to suggest improvements, typically foam panels for this project.

I am very happy to do this mission because I can put the lessons I learnt this summer into practice. My two teammates were surprised that I was taking measurements thoroughly, but I knew from my experience this summer that I these dimensions would be very important for the computer modeling. I was also very happy to use a decibel-meter and an omnidirectional source of sound.

That’s it for this week! If you remember well, I visited Faurecia a few weeks ago. I had the chance to talk with a top-engineer there and he gave me some documents so I could do a specific article about it! Probably next week or the week after!
