NewPing Library: HC-SR04, SRF05, SRF06, DYP-ME007, Parallax PING))) - v1.7

Unfortunately for me, I am using the tone library and wanted to use the NewPing library too.
Do you know any way around the conflict?
It can be also a new tone library (or a modified one) or another way of playing a tone without the usage of the Timer2

TIA,
basile
