The inside of the box is lined with two layers of a sound deadening material. In the images below this is the silver layer. It is a dense material which is made to absorb sounds for vehicles. <\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">There is an acrylic window on top, so the user can see the keyboard, which is two layers thicks. There is an air gap between the layers to try and further increase sound isolation. <\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The box is closed on all sides except where the user inserts their hands. The closed sides are tightly held together to improve sound isolation.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The sound proofing material creates significant echoes inside the box since the sound cannot leave easily. To fix this we padded the inside with sound absorbing foam. This is very light material and often used in home studios help with reducing reflecting sounds<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The sound proofing box is quite effective. We found it can reduce the noise level by 15dB, using an app on my phone to test. We hope this box will help increase our accuracy by significantly reducing the noise in the loud demo environment.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-108\" src=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status3.jpg\" alt=\"\" width=\"1124\" height=\"843\" srcset=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status3.jpg 1124w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status3-300x225.jpg 300w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status3-768x576.jpg 768w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status3-1024x768.jpg 1024w\" sizes=\"(max-width: 1124px) 100vw, 1124px\" \/> <img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-109\" src=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status2.jpg\" alt=\"\" width=\"477\" height=\"358\" srcset=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status2.jpg 477w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status2-300x225.jpg 300w\" sizes=\"(max-width: 477px) 100vw, 477px\" \/> <img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-110\" src=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status1.jpg\" alt=\"\" width=\"1204\" height=\"903\" srcset=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status1.jpg 1204w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status1-300x225.jpg 300w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status1-768x576.jpg 768w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s19-teama2\/wp-content\/uploads\/sites\/17\/2019\/05\/status1-1024x768.jpg 1024w\" sizes=\"(max-width: 1204px) 100vw, 1204px\" \/><\/p>\n<h3><span style=\"font-weight: 400\">Upcoming Work<\/span><\/h3>\n<p><span style=\"font-weight: 400\">Next week is the final demo and report.

The box is 26inches x 18inches x 6inches and can house full sized keyboards. An acrylic window was cut into the top to allow easy viewing of the keyboard. <\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">I wrote a simplified version of the code for the demo, allowing for quick input of a recording of an audience member\u2019s typing. <\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400\">Upcoming work<\/span><\/h3>\n<p><span style=\"font-weight: 400\">The only upcoming work is the demo and the final report. We will also record a demonstrative video in case the noise levels in the demo room make effective classification impossible. <\/span><\/p>\n<h2>Ronit<\/h2>\n<h3><span style=\"font-weight: 400\">Accomplishments<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Built the sound proof box and evaluated its effectiveness by collecting data and trying to infer passwords.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">We found that the box reduces outside noise by about 20 dB.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Setup the esp32 for demo, temporarily disabled power saving mode. (the demo room will be too noisy for the esp to go to sleep).<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Tested the project against a mechanical keyboard. We found that our algorithm works better for membrane keyboards, but this might be because we tuned our parameters for a membrane keyboard.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Performed user tests(with people other than me kevin and james).<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Worked on video for demo, in case te demo does not work in the noisy demo room.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Worked on final report.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400\">Upcoming work<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Work on the final report.<\/span><\/li>\n<\/ul>\n<h2>Team Status<\/h2>\n<h3><span style=\"font-weight: 400\">Accomplishments<\/span><\/h3>\n<ul>\n<li style=\"list-style-type: none\">\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This week, the team worked closely together to construct a soundproofing box to try to maintain a moderate sound level during the demo. <\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Slightly simplified versions of the signal processing and ESP32 code were written to allow for a more demonstrable project. <\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400\">Upcoming work<\/span><\/h3>\n<p><span style=\"font-weight: 400\">In the next week, we will be demoing our project and writing the final report. <\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kevin Accomplishments This week I helped james build a soundproof box he designed.
