We study by numerical means the MHD oscillations in a solar coronal loop. Obtained numerical results show that impulses, which are launched in the ambient plasma, excite oscillations in mass density profiles that reveal asymmetry in a cross-section of the loop. This asymmetry is a consequence of the fact that while a part of the loop is compressed its other part is rarefied, resulting from transverse loop oscillations. Due to a lack of spatial resolution this feature has not been observed in the earlier numerical studies of impulsively generated waves. The numerical simulations reveal distinctive time-signatures which are collected at a detection point inside the loop. For the chosen set of physical parameters, these signatures reveal a dozen or so seconds oscillations in the mass density. These oscillations are usually more complex further out from the trigger. A sufficiently large slow magnetosonic wave generates shocks which temporal evolution we trace in mass density profiles.
