The name of the Sound in the local Gaelic language is An Lighe Rathairseach, from the island of Raasay which lies along the Sound's western side. This name very similar to the name given to the straight on the west of Raasay, An Linne Rathairseach (known in English as the Sound of Raasay). Together, the two sounds, the Inner Sound and the Sound of Raasay, may be considered as southeastern arms of the Little Minch.
BUTEC, a Royal Navy submarine sensor and emissions range, is emplaced in the Inner Sound.
