We know sound. We get involved in research projects about sound, conduct our own tests, have constant dialogues with acousticians and people that are affected by sound in some way. Moreover, we know how sound affects people.
Me tunneme heli. Me oleme seotud paljude heli-teemaliste uurimistöödega, viime läbi omapoolseid testimisi, suhtleme pidevaltakustikuste ja inimestega, kes on muul viisil seotud helidega.
