Auralization

The English term auralization was used for the first time by Kleiner et al. in an article in the journal of the AES en 1991.^[1]

The increase of computational power allowed the development of the first acoustic simulation software towards the end of the 1960s.^[2]

Auralizations are experienced through systems rendering virtual acoustic models made by convolving or mixing acoustic events recorded 'dry' (or in an anechoic chamber) projected within a virtual model of an acoustic space, the characteristics of which are determined by means of sampling its impulse response (IR). Once this ${\displaystyle h(t)}$ has been determined, the simulation of the resulting soundfield ${\displaystyle s(t)}$ in the target environment is obtained by convolution:

${\displaystyle r(t)=h(t)*s(t)}$

The resulting sound ${\displaystyle r(t)}$ is heard as it would if emitted in that acoustic space.
