DeepGrade vs NoixApp

DeepGrade is an ideal app for both Tutors and students. Where teachers would be able to record video of their lessons and publish to students and students from the comfort of their mobile phones will be able to access them. The tutors will also be able to set Quiz, Assignments, worksheets ans assign to students. Students would be able to take quizzes and also submit assignments by clicking pics of the assignments and send them back for feedback from teachers.Also they would be able to share and send documents for the students to download and consume.

Among the many forms of pollution in urban areas, acoustic pollution is one of the less considered, albeit very important for the public health and welfare. Being less popular it is also less known and accounted for, so that few initiatives exist in this field. These are generally based on systematic surveying practices based on fixed stations only which cannot reconstruct a full picture of the acoustic spaces of the cities. A new perspective is necessary. Noixapp is a crowdsourcing/citizen-science solution developed by the National Institute of Oceanography and Applied Geophysics - OGS, to measure acoustic pollution in urban areas that uses inexpensive mobile phone microphones to acquire data on urban background noise and send it to an integration platform that allows to reconstruct a full picture of the acoustic space of an area. The solution is based on a mobile application software where it is possible to record, compute and average Sound Pressure Level values. Georeferenced data are transmitted to OGS facilities where they are anonymized, integrated, validated and mapped on an open-data web based portal. SPL can be calibrated by using external reference instruments.
