Portable audiometer for detecting hearing disorder at an early stage for cancer patient

Cancer treatment requires heavy dose of drugs which can affect hearing capacity. In such case it is very essential to monitor the hearing capacity of the patients continuously so that hearing disorder can be detected at an early stage. Portable audiometer can prove to be a powerful tool for preventing the hearing disorders in patients. Portable audiometer consists of a hardware unit which is connected to a pair of earphone and a patient response switch. The frequencies of the audible range are transmitted to the patient through the ear phone. The recorded response is transmitted to the health care unit. This paper describes the design technology of portable audiometer which includes audible range test functionality and is capable of early detection of hearing changes. The system includes a wireless cellular modem which is capable of notifying a remote healthcare professional of the hearing test result.
