Noise is the most frequent cause of disputes between neighbors regarding emissions, especially in condominium settings. Article 844 of the Civil Code states that noise, smoke or heat emissions, fumes, vibrations, and similar propagations are unlawful if they exceed the "normal tolerability".
ABOUT US
The maximum permissible limits of noise coming from internal sources of the building where the disturbance occurs
Article 6 – Acceptability Criteria for External Environmental Noise
1. Noise Exposure Limits by Area Type
The evaluation sound level (Lv), referring to all noise sources external to the disturbed location—excluding road traffic noise, which is regulated under separate legislation—must not exceed the maximum permissible values indicated below:
| Area Type | Daytime | Night-time |
|---|---|---|
| Industrial areas | 70 dB(A) | 70 dB(A) |
| Craft/artisan zones | 65 dB(A) | 55 dB(A) |
| Urban residential areas with significant commercial activity | 60 dB(A) | 45 dB(A) |
| Other urban residential and agricultural areas | 55 dB(A) | 45 dB(A) |
| Areas with hospitals, clinics, schools, retirement homes, etc. | 45 dB(A) | 35 dB(A) |
These values are expressed in A-weighted decibels [dB(A)] and refer to the equivalent continuous sound level (Leq), in accordance with ISO 61672-1 and ISO 1996-2.
2. Reference Time Intervals for Noise Assessment
The Lv must be calculated over the following time periods:
Daytime: the four most disturbed consecutive hours;
Night-time: the most disturbed consecutive 30 minutes.
📝 Technical Note: These intervals are selected based on ISO 1996-2, which emphasizes evaluating noise according to actual human perception and sensitivity to annoyance.
3–4. Noise Emitted from Within the Same Building
When the noise source is located within the same building as the disturbed room, more restrictive limits apply. These are based on the differential between the ambient (background) level and the measured noise:
Daytime Limits
Lv over the 2 most disturbed hours must not exceed background noise by more than 3 dB(A);
Lv over the 3 most disturbed minutes must not exceed background noise by more than 5 dB(A).
Night-time Limits
For variable noise, Lv over the most disturbed 30 minutes must not exceed background noise by more than 1 dB(A);
For constant noise, the level measured with a "slow" time weighting must not exceed background noise by more than 1 dB(A) (in the absence of both the noise source and traffic).
📌 Technical Insight: A 3–5 dB(A) increase is typically just perceptible to the average human ear; increases beyond this threshold are generally classified as disturbing.
5. Pure Tones and Impulsive Sounds Not Considered
The presence of pure tones, impulsive or periodic sounds is not included in the Lv calculation under this article. However, they may aggravate perceived annoyance and should be assessed separately, following ISO 1996-1 and ISO 1996-2 recommendations.
6. Exceptions for Musical Instruments and Mixed-Use Buildings
The limits in point 4 do not apply:
to noise generated by musical instruments;
to residences located in mixed-use buildings where commercial or industrial activities take place and that are situated in industrial or artisan zones.
7. Noise from Common Building Services
For common technical services (e.g., heating, air conditioning, plumbing, etc.), the maximum allowable noise levels, measured using A-weighting and "slow" time constant, are:
40 dB(A) for intermittent systems;
30 dB(A) for continuous systems.
🔍 Standard Reference: These thresholds are aligned with ISO 16032, concerning the acoustic performance of technical building services.
8. Exemptions for Existing Buildings
In exceptional cases where complying with these limits is proven to be technically or economically infeasible, an exemption may be granted by the competent provincial authority, based on the binding opinion of the 1st Section for Environmental Hygiene, as defined by Article 10 of Provincial Law no. 2 of January 20, 1984.
9–10. Noise Measurement Procedures
Measurements of centralized systems (heating, ventilation, elevators) must be performed in the most affected room, typically one that requires the highest level of acoustic comfort.
Noise from plumbing, toilets, drainage systems, and taps must be measured in a different apartment than the one where the noise originates, to ensure neutral and unbiased readings.
