Τι είναι η ηχοπαγίδα;

Ηχοπαγίδα είναι μια διάταξη αεραγωγού, η οποία επιτρέπει τη διέλευση του αέρα, ενώ ταυτόχρονα αποσβένει μέρος του θορύβου της εγκατάστασης στην οποία τη χρησιμοποιούμε. Η ηχοπαγίδα μπορεί να είναι ορθογωνικής ή κυκλικής διατομής και μπορεί να αποτελεί μέρος ενός δικτύου αεραγωγών (σύστημα κλιματισμού - εξαερισμού) ή να τοποθετείται ελεύθερη στο άνοιγμα μιας επιφάνειας χώρου, όπου χρειαζόμαστε αερισμό και ηχομόνωση. 

Are mineral wools (rockwool,glasswool) or PU foam materials sound insulating?

I live in an apartment and I face noise problems from other apartments or facilities. What could I do;

Generally if the noise is related to speech, TV etc. (generally airborne) significant improvement in sound insulation can be achieved by applying appropriate noiseproofing linings in the boundary surface (horizontal or vertical partition) between your room and the room that the noise comes from.

If the noise is structure-borne (footfall noise etc.), the soundproofing of the boundary surface is not sufficient, as it may result in little or no improvement in sound insulation and different treatment is required.

For proper assessment of the problem, a qualified engineer should investigate the kind of the noise and the way the noise propagates.

Airborne and structure borne noise?

Airborne noise is any unwanted and unpleasant sound that propagates through the air.

The structure borne noise is transmitted through solids, ie the structural elements of a building. One of the main categories of structure-borne noise is the impact noise.

Noise definition

Noise is any unwanted and unpleasant sound, which can cause adverse effects such as irritation, difficulty communicating, hearing loss etc.
