This report will broadly cover the area of consumer electronics with regards to hearing impaired patients and how such devices can be further improvised for other purposes and operations. An existing prototype was able to embark such technology to the existing walkie‐talkie and making the communication between two parties to become tactical conversation. This project involves that development and construction of a remote wireless activation method of the PTT function for the mobile phone and a wireless form of voice signal transmission from the mobile phone to the end receiver which is the hearing aid ear piece. There are 2 physical devices which are the remote PTT transmitter and PTT receiver that will be connected to the mobile phone. The communication technology for the remote PTT control is using 433MHz radio frequency and the receiver side also using magnetic induction for the transferring voice to the hearing aid.
