Hi
This is my first post in this forum , and i am in need of help, very much to this post.hope you guys wont disappoint me.
First of all i am planning to implement a circuit,a so called energy saver hearing aid(that uses battery for amplifying stages in case when sound is detected), which has schematics as given below.I am aware that this needs lots of improvement in design , the main problem that i face is that what sort of earphone should i use,as sound is amplified to a very good extend ,what should be the voltage ratings? do i need any extra driver circuitry,as i dont have any preknowldge about earphone driving,and above all many more tips and improvements in design to realize this practically.
Thanks in advance
