It's like saying with "dates" that the requirement is to be born before 1900 and to die at least after 1950, so of you are born before it's better. The other end is represented by 20khz, for this one the bigger the better.(10-04-2014, 03:33 AM)maniac360 Wrote:(10-04-2014, 03:25 AM)zen Wrote: Is it bad to have this frequency response ?
No, even with ultrasonic it's ok (20hz to 20khz minimum for ultrasonic). Most earphone/earbud will play fine. It's only the speaker that are hard to find because they usually cost a lot more. I have bought earphone for 15 bucks and they can play ultrasonic.
Maniac u meant to say since it is 5hz it covers 20hz minimum freq. response ? or what I am not clear man
Thank you for your helpful response. I want to know more if I buy noise cancelling in ear headphone will it hamper ultrasound by any chance and I need to speak with others when I work but I can take liberty to keep my headphone in ear during work but I have to respond them to communicate. What do you think ?
Long ago I read that Shannon doesn't recommend using headphones with noise cancellation feature.
