This paper describes the computation of the acoustic insulation provided by a single simple wall separating two contiguous tunnels when a steady state, spatially sinusoidal, harmonic line load pressure excites one of the tunnels. The Boundary Element Method (BEM), formulated in the frequency domain,

## Communicated by W. Sprößig The diffraction of acoustic waves by an infinitely long annular duct having a finite gap on the inner wall is investigated rigorously. The related boundary-value problem is formulated into a modified Wiener-Hopf equation, which is then reduced to a pair of simultaneou
