[1] A manuscript is made up of lines and spaces, and these lines and space have their names depending on the staves (bass or treble). Manuscript paper is also available for drum notation and guitar tabulature ...
Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.

Generally speaking, they can be written on paper or parchment. If the manuscript contains the composer's handwriting it is called an autograph.
The acoustic pressure in a cylindrical duct can be expressed as the superposition of duct modes: p = ∑ α i ϕ i {\displaystyle p=\sum \alpha _{i}\phi _{i}} where α i {\displaystyle \alpha _{i}} is the participation factor or modal amplitude and ϕ i {\displaystyle \phi _{i}} is the mode shape.
The music written for drummers is not the same as, say, a pianist. Drummers use their own symbols and language in their charts. For example, a "middle C" note written on a staff for pianists is equivalent to the "snare drum" for drummers. Or, the note "F" on the piano staff is equal to the "bass drum." There is no set standard for writing drum ...
As indicated in GR-3155, cable is typically placed into the duct in one of three ways: It may be pre-installed by the duct manufacturer during the extrusion process. It may be pulled into the duct using a mechanically assisted or hand-drawn pull line. It may be blown into the duct using a high air volume cable blowing apparatus.
