Introduction and Objectives: The popular manifestations associated with the festive use of ancient weapons or muzzleloader replicas have numerous and ancient references throughout our geography, but there was a lack of studies of the novel sounds derived from their use. A work was designed that would allow the analysis of the noise levels generated, in order to guide protection measures to its users.
Material and method: Data from 24 weapons of 22 different types were collected, determining different measurement points, and the sonometric results were analyzed according to the types of weapon, distance to the shooter and frequency range.
Results: The data obtained demonstrate higher sound levels for the bass tones, with averages of 102 to 117dB measured one meter from the shooter, with little attenuation at distances at 5 and 10 meters and without clinically relevant differences derived from the type of weapon. distance or powder charge. Conclusions: The sound levels generated by muzzleloaders advise recommending the appropriate protection measures, not finding clinically relevant differences for the different types of weapons used.
