"Early warning of approaching aircraft was recognized as a priority as early as WW1." Before radar these "ear amplifiers" were "manned by personnel to listen for aircraft. "The amplifiers were "miniaturized" by folding the hearing tubes (into a trumpet shape)and by making them "portable" by mounting them on trailers."
