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

• thers 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.
