The inner surface encompasses a cavity with an opening, and a microphone arrangement is configured to pick up sound with at least one steerable beam-like directivity characteristic, and to provide a first electrical signal that represents the picked-up sound. The earphone further includes an active noise control filter configured to provide, based on the first electrical signal, a second electrical signal, and a speaker disposed in the opening of the cavity and configured to generate sound from the second electrical signal. The active noise control filter has a transfer characteristic that is configured so that noise that travels through the shell from beyond the outer surface to beyond the inner surface is reduced by the sound generated by the speaker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active noise reduction earphones","description":"An active noise reducing earphone includes a rigid cup-like shell having an inner surface and an outer surface is provided.
