1 | Why Sound Matters When Buying Properties in Estonia

A “quiet” flat commands better livability, fewer tenant complaints, and stronger resale. When buying properties in Estonia, evaluate both external noise (traffic, trams, nightlife) and internal noise (neighbours, plumbing, lifts, HVAC). Newer builds often perform better—but only when the acoustic class and installation quality match the brochure.

2 | Acoustic Basics (Plain English)

Airborne noise (voices/music): measured via wall/ façade performance (look for Rw/DnT,w values).
Impact noise (footsteps): measured at floors/ceilings (Ln,w—lower is better).
Façade noise: windows + wall + vents = the real result; weak links ruin performance.
Room echo: hard surfaces amplify sound; rugs and soft furnishings help.

Quick rule: For bedrooms, aim for ~30–35 dB at night with windows closed.

3 | Site Visit Checklist (Copy/Paste)

☐ Time your visit at evening rush or weekend night if near bars/trams
☐ Stand still for a minute: fridge, elevator, ventilation hum?
☐ Footfall test upstairs: ask a friend/agent to walk—any thuds?
☐ Windows: multi-chamber frames, proper seals, trickle-vents closed?
☐ Bathrooms: fan noise, pipe gurgle on flush
☐ Bedrooms facing quieter courtyard, not street

4 | What to Request From Seller/Developer/HOA

Acoustic design summary (target class and tested values, not just marketing claims)
Floor build-up (floating screed, underlay type, thickness)
Façade/window spec (glass build—e.g., laminated/laminated + air gap)
Apartment-level ventilation details (through-wall vents vs ducted HRV)
Any post-handover complaints and fixes (HOA minutes)

5 | Windows & Façades—Your Primary Shield

Feature	Why It Helps	Buyer Tip
Laminated glass	Damps vibration and high-frequency noise	Ask for asymmetric panes (e.g., 8.8/16/6) on street side
Deep air gaps	Better low-frequency control	14–20 mm gaps often outperform tiny gaps
Quality seals & frames	Stops whistling and leaks	Test with a sheet of paper: should grip firmly
Acoustic trickle vents	Fresh air without big noise penalty	Check that vents actually close for night

6 | Floors & Impact Noise (The Thud Factor)

Look for a floating floor: resilient underlay + screed separation from walls.
Skirting detail: there should be a soft strip behind, not hard-bonded screed.
Tile-on-concrete with no underlay = risk for clacking footsteps above.
In older stock, add underlay and rugs; in new builds, confirm Ln,w targets.

7 | Building Services Noise

Lifts: corner flats next to lift shafts need extra checks (ride the lift and listen).
HVAC: fan-coil/HRV should be quiet on low; query sound pressure levels (SPL).
Plumbing: vertical stacks behind bedroom walls can transmit flush noise.

8 | Negotiation Levers

Ask for window upgrade (laminated street-side) or seal replacement.
Request underlay spec proof for floors above/below.
If measured noise is high, negotiate price relief or seller-funded works.
