Diffuser (automotive)
A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of th ...

Sound diffuser
Diffusion, in architectural acoustics, is the spreading of sound energy evenly in a given environment. A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position.
Most interior spaces are non- ...
, a device that scatters reflections of sound across frequencies

Diffuser (breathing set part)
A scuba set, originally just scuba, is any breathing apparatus that is entirely carried by an underwater diver and provides the diver with breathing gas at the ambient pressure. ''Scuba'' is an anacronym for self-contained underwater breathing ...
, a device fitted over an underwater breathing set's exhaust orifice to break up the gas outflow
* Diffuser (hair), a
blowdryer
A hair dryer, hairdryer or blow dryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. Blow dryers enable better control over the shape and style of hair, by accelerat ...

Diffuser (thermodynamics)
A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a ...
, a device that controls the characteristics of a fluid at the entrance to a thermodynamic open system

Reed diffuser
Aroma lamps, or diffusers, are used to diffuse essential oils. They may project the oil into the air by heating it, letting it evaporate naturally, or nebulizing it using compressed air or ultrasonics.
