Example methods disclosed herein to embed information in an acoustic signal output from an electric vehicle include obtaining a first audio signal to be used to generate the acoustic signal. Such example also include combining a second signal with the first audio signal, the second signal to convey first digital information that, when detected, indicates a presence of the electric vehicle. Such example methods further include providing the first audio signal with the second signal to an audio circuit that is to output the acoustic signal from the electric vehicle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Embedding information in generated acoustic signals","description":"Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to embed information in generated acoustic signals are disclosed.
