Resident videos, observations and indicative Decibel X readings document the intensity, character and timing of noise heard from nearby homes.
The documents supplied by the Junta do not show that the complete kart fleet, normal public operation or the busiest and noisiest conditions were properly assessed.
The 2020 study identified 23 karts: 15 Honda GX120, four GX200 two seaters and four GX270 karts. The 2024 report describes 15 GX120 karts and apparently tests only 12, without explaining what happened to the remaining vehicles or whether the other types were assessed.
The measurements took place on 11 June 2024, before the circuit reportedly opened to the public at the end of July. The report does not demonstrate that ordinary customers, Grand Prix events, repeated sessions or peak weekend conditions were reproduced.
Normal sessions last approximately ten minutes and competitive formats can involve several sessions. Three five-second samples cannot show how noise develops as drivers become faster and more competitive.
The reported result was 59 dBA against an applied limit of 60 dBA. The report itself states a measurement uncertainty of ±2 dBA.
The technical support consists of a one-page manufacturer statement. It does not include independent test results or demonstrate that the silencers or dB killers are installed, maintained and functioning correctly on every operational kart.
The assessment does not demonstrate that it captured the full effect of tyre screeching, whistles, cheering, clapping and award ceremonies associated with organised events.

Playback is voluntary and audio never starts automatically. The video files have been made web-compatible without changing their original audio streams.
Both resident screenshots below record maximum readings above 70 dB. They are useful evidence of what residents experienced, but a new regulatory acoustic assessment by an independent accredited body is required to determine compliance using the prescribed methodology and measurements taken at affected flats.
Consumer readings for context only. They are not regulatory measurements and do not, by themselves, establish compliance or non-compliance.
Decreto 50/2025, Article 28 and Table VII, sets activity-noise immission limits for predominantly residential areas at 55 dBA by day, 55 dBA in the evening and 45 dBA at night. The prescribed methodology and acoustic classification must be used.

Residents are asking for an urgent inspection and a new regulatory acoustic assessment by an independent accredited body that measures impact from several affected Sunset Views Phase One flats, rather than relying only on positions at or immediately beside the track. The review should also account for the additional homes now occupied next to the site and the further phases due to open.
