Noise in Aarau-Olten: best neighborhoods and areas

The Noise criterion evaluates chronic sound exposure: road, rail, air, and industrial noise. It draws on the FOEN SonBase model and the BAZL air-noise cadastre. A high score means a calm environment, conducive to sleep and concentration.

On this criterion, the Aarau-Olten area shows average results. The average score of 8.8/10, computed across 143 communes, sits on par with the national average (8.9/10). Scores span from 5.3/10 to 10/10 across the communes analysed.

The standard deviation of 1.2 signals moderate variation between communes, enough to warrant a careful comparison.

Geographic Patterns and Contrasts

The spread between the top-ranked commune (10/10) and the weakest (5.3/10) reaches 4.7 points. The agglomeration offers contrasting profiles without marked homogeneity.

Top-ranked communes typically benefit from several convergent factors (location, long-standing infrastructure, geographic exposure); the weakest often compound structural disadvantages. The interactive map makes these spatial clusters visible at a glance.

Who Weighs This Criterion Most

Among the four VivaMap profiles, the Nature profile weights this criterion most heavily (weight 95 out of 100). The other profiles apply the following weights: Family (weight 90), Retirement (weight 90), Young Professional (weight 30).

Practically, a high Noise score carries significant impact on the ranking for the Nature profile, whereas it matters less for a profile that de-emphasises this criterion. This explains why the same commune can lead one ranking and fall mid-pack in another.

Comparison Across Swiss Agglomerations

Among the 21 major Swiss agglomerations analysed by VivaMap, Aarau-Olten sits in the lower half for Noise — rank 12/21 (ahead of 48% of the agglomerations).

Its immediate neighbours in the ranking are St. Gallen (rank 11) and Thun (rank 13). This context helps calibrate absolute scores: an agglomeration that looks average in isolation can sit well among its peers, and vice versa.
