Using multistrand wires for an ultrasonic transreceiver

[raybuzz]

I was recently doing a project on a ultrasonic transreceiver, and was adviced to use thin multistrand wires for rigging the circuit., for reducing signal noise. I am not able to understand why we need to use multistrand wires, or if they help in reducing noise, how they help. Because i find soldering and making a circuit with single strand wires(thin) is much easier, than using multistrand.

Were they maybe referring to Litz wire? Standard stranded wire will have a little lower inductance than solid wire, but not by as much as Litz wire.

Yes i think so it was the same kind of wire they were referring to, (though i got confused and ended up using normal thin multistrand). Is it the same kind of wire used in earphones?

Litz wire is mainly used in high-end speaker cables, and probably some other specialized applications. Check out the wikipedia.org page for more info. Welcome to the PF, BTW.
