A microphone is arranged in a pillar trim of a motor vehicle. Shortly thereafter, assembling devices obtain the fragments and reconstruct the segments at a rate that allows approximately real-time presentation of the streaming content including the segments. Alternatively, the acoustic device may be mounted directly to the panel without the use of the attachment member. The elongate member has a wall material imparting a stiffness to the elongate member. The method may further include determining a first two dimensional distribution for points in the first EGI segment and a second two dimensional distribution for points in the second EGI segment. The local oscillator apparatus comprises at least one mixer coupled to an oscillator input signal and to a feedback signal such that a local oscillator signal may be produced by fractional multiplication of the oscillator input signal.
