A sound insulating element comprising:
- a body made of a mineral fibre material and having a single layer structure and acoustically insulating properties, the body comprising a front surface, a rear surface, and a side surface connecting the front and rear surfaces;
- and
- a plurality of acoustic resonators distributed in a rear surface portion of the body or over the rear surface of the body,
- wherein the plurality of acoustic resonators has a mass inclusion rate between 5% to 30% in relation to a mass of the body, and
- wherein each resonator is configured to have a resonance frequency essentially corresponding to a compressional wave frequency of the body, and
- wherein each of the plurality of acoustic resonators has a cylindrical or cuboid shape.
