Lauri Marjamaa and Heikki Kossi, both Finnish sound designers, played a crucial role in the sound design team of the Oscar-winning short documentary 'All the Empty Rooms,' directed by Joshua Seftel. This documentary honors the memories of victims of school shootings by showcasing the empty bedrooms of children who lost their lives in these tragic events. The film features contributions from CBS journalist Steve Hartman and photographer Lou Bopp, who captured the impactful visuals that accompany the poignant narrative.

In the documentary, Marjamaa expresses his pride in being part of such a significant project, describing the winning of an Oscar as an exhilarating experience. However, he also acknowledges the somber nature of the documentary's subject matter, which serves as a stark reminder of the realities surrounding school shootings. The emotional weight of the content is highlighted by Marjamaa's comments, emphasizing that while the accolade is significant, it must also be viewed in the context of the heavy themes addressed by the film.

Lauri Marjamaa and Heikki Kossi aimed to create a soundscape that enhances the emotional gravity of the empty rooms depicted in the documentary. Their work involved capturing foley sounds that resonate with the visuals, aiming to instill a profound sense of emptiness within the audience. Podme, the platform where Marjamaa works, highlighted the importance of their role in making the auditory experience align with the film's powerful message, ultimately reinforcing the impact of the documentary on viewers.
