Spider silk can make hearing aids better
It has been discovered that fine fibers like spider silk can improve the quality of microphones in hearing aid.
A study in the USA has found that this could greatly improve the hearing quality of hearing aids used by hard of hearing people.
The microphones using the silk become more sensitive and can catch sound frequencies that are not felt by the normal hearing aids.
The same effect can also be produced by very fine fibers if used to make the microphones.
This would increase the sound range and help hear much better as compared to the currently used microphones.
