Vision Document: Problem Statement ● The problem of. ○ Hearing impairment ● Affects. ○ Individuals with hearing loss ● The impact of which is. ○ The need to purchase a hearing aid device; which can cost $4,000 or more. ● A successful solution would be. ○ An inexpensive smartphone application that can provide hearing aid functionality by leveraging the phone’s built in hardware.

Vision Document: Stakeholders ● Friends, Family, and Co-Workers of the hearing impaired. ● App Dev Team ● Teacher’s Assistant ● Professor Chung

WRS: Problems ● P1 ○ The hearing impaired cannot hear what is happening around them. ● P2 ○ Also, they cannot hear others easily enough to communicate with others. ● P3 ○ While hearing aids exist for this purpose, they are too expensive for many hearing impaired people to afford.

WRS: Goals ● G1 ○ Create a free hearing aid application that can work with any smartphone. ● G2 ○ Create a hearing aid application that will allow the hearing impaired to hear what is happening around them. ● G3 ○ The application should also make communicating with others easier by allowing them to hear the person they are conversing with more easily.

WRS: Functional Requirements ● FR1 ○ The system shall amplify all sound that can be received by the phone microphone (20Hz - 20kHz) to 70+ dB through headphones. ● FR2 ○ The system shall isolate and then amplify human speech. ● FR3 ○ The system shall dynamically adjust minimum volume levels from 0 dB output to 70+ dB output independently for each headphone (left and right).

WRS: Non-Functional Requirements ● NFR1 ○ Audio amplification and isolation will run outside of the application, and within it. ● NFR2 ○ Amplification of input audio will have a maximum latency of 30ms. ● NFR3 ○ Audio will only be stored in the phone’s memory, never on disk. ● NFR4 ○ Audio output will not cause more harm to the user’s hearing.
