![]() Since our device is independent of the actual user, the uniqueness of someone’s hearing disability doesn’t affect our device and the way it operates. How long does it take your system to process the signal?Ħ) Do you expect ambient sounds to have a similar frequency profile as a whistle from a ref? I have sat in many a spectator stand with cow bells and other annoying noise makers!ħ) What is the frequency range of your detector? Do you have any amplification of the signal? Log in to Replyġ) Our device doesn’t actually depend on someone’s hearing disability. How does your design accommodate the acceptance of sound waves and reject water and dust?ĥ) Based upon the speed of sound, what delay might the user experience from a sound such as a whistle being blown to detection? I think you could reasonably scope your calculation to a typical sports field. How do you accommodate that in your design?Ĥ) The double edge sword is that any environmental protection will inhibit the sound wave from penetrating the housing. Does your system filter any of that noise? If so, would you recommend a band pass, low pass or high pass filter and why?ģ) Your housing needs to be water and dust proof. Can your system be adjusted for the specific user?Ģ) You can expect a wide frequency profile of the ambient noise at a sporting event. When fitting hearing aides, the audiologist uses very sophisticated tests to profile the frequency of loss and the required amplitude adjustment required for correction. Clearly one that needs a solution! Hearing aides are VERY expensive!ġ) Everyone’s hearing loss is unique. I like that you identified a very unique problem. ![]()
