Provided are: a muffler that can suitably obtain an attenuation effect of a sound wave; and a muffling device including the same. The muffler is installed on a wall surface of a pipe conduit where a gas flows. The muffler includes: a front surface exposed to an inner surface of the pipe conduit; a bottom surface facing the front surface; and a side surface disposed between the front surface and the bottom surface and covering a space between the front surface and the bottom surface. The front surface is formed with a plurality of through-holes, and the number of through-holes arrayed in a gas flow direction is one or two, and the number thereof arrayed in a direction orthogonal to the gas flow direction is 10 or more.

A vibration-damping material which can be arranged without gaps along the shape of the outer surface of a base material, that is, a vibration-damping material which is attached to a convex curved outer surface of a base material and comprises a vibration-damping member capable of bending deformation and having multiple cuts in an attachment surface to be adhered to the outer surface, thereby dividing the attachment surface into multiple blocks, with the surface of each block opposite the attachment surface being formed connected to each other.

Provided is a steam turbine in which, among a plurality of stages thereof, a stage that is disposed furthest upstream is a speed-adjusting stage, at least one stage that is disposed downstream of the speed-adjusting stage is a medium-pressure stage, and at least one stage that is disposed downstream of the medium-pressure stage is a low-pressure stage. The speed-adjusting stage is an impulse stage. The medium-pressure stage is a medium reaction degree impulse stage in which the degree of reaction is a medium degree of reaction of 10-40%. The low-pressure stage is a reaction stage having a higher degree of reaction than the medium-pressure stage.
