There could be some improvement with labeling your graphs but all in all a very good blog with little to complain about.

However, it made sense from my previous biology/physics knowledge about the human threshold of hearing which is about 20 Hz to 20 kHz. We probably couldn't hear 15 kHz due to the room being noisy. A dog would be able to hear it though! Their threshold of hearing is between 67 Hz and 45 kHz.Nick Polegahttps://www.blogger.com/profile/08576093897836151309noreply@blogger.comtag:blogger.com,1999:blog-2634427411038711641.post-48944250508685831912017-03-19T21:28:03.216-07:002017-03-19T21:28:03.216-07:00That is very interesting that you had a shape simi...That is very interesting that you had a shape similar to a parabola for a high pass filter Joe I can not think o any good reason that your graph would look like that unfortunately!

Also, we ended up hearing a sound from the speaker at 10Hz!! You guys did a great job on the lab though! Very similar data.

Where did you guys find your microphone's resistance value online, we looked pretty hard and had barely any luck finding it. Great explanations, they helped us understand the different filters.gggghttps://www.blogger.com/profile/04487372781227426394noreply@blogger.comtag:blogger.com,1999:blog-2634427411038711641.post-13691469769039468012017-03-19T17:28:28.718-07:002017-03-19T17:28:28.718-07:00I liked you video of your explanation of the micro...I liked you video of your explanation of the microphone circuit. It was really hard to get ours to work. I ended up finding out from another group that your circuit could be set up correctly, but if your headphone is too advance like the 3 or 4 rings that are on most headphones you wouldn't be able to hear any sound because the jack and headphones weren't compatible not because the circuit itself is wrong.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2634427411038711641.post-78983852863678366592017-03-19T16:51:29.504-07:002017-03-19T16:51:29.504-07:00Nice job this week. it seems like everyone got don...Nice job this week. it seems like everyone got done pretty fast, I'm wondering if the holiday on friday had anything to do with that. We had a few differences for our blog. we calculated a resistance on our speaker of 9ohms and then our high pass filter graph had a different shape than yours. ours was incorrect and had a shape similar to a parabola. im not sure why this could be, do you have any ideas?Anonymoushttps://www.blogger.com/profile/08172897676744227243noreply@blogger.com
