Regulación acústica de Hibiscus rosa-sinensis frente al ruido vehicular en Iquitos, PerúArticle Sidebar
Main Article Content
Context: Introduction: urban vehicular noise significantly impacts environmental quality, necessitating green infrastructure solutions. Objective: to quantify the effectiveness of Hibiscus rosa-sinensis L. barriers in reducing vehicular noise along La Marina Avenue in Iquitos, Peru. Methods: the study adopted a quantitative, cross-sectional, and comparative design, focusing on continuous H. rosa-sinensis barriers. Purposive sampling was performed at six locations across the EsSalud and Bellavista Nanay sectors. Acoustic measurements utilized a Class 1 integrating sound level meter (IEC 61672-1:2013) following ISO 1996-2:2017 and MINAM protocols. Three conditions were compared: open field, Position A, and Position B. Results: the barriers had a mean height of 1.208 ± 0.066 m and a width of 1.008 ± 0.080 m. The open field LAeq,T was 74.63 ± 2.16 dB(A), exceeding environmental quality standards (ECA) at 100% of the sampling points. Position A showed a significant reduction of 2.90 ± 1.05 dB(A) (U=30.0; p=.033; r=.667), whereas Position B showed no significant difference (p=.120). Conclusion: H. rosa-sinensis provides measurable acoustic regulation; however, its effectiveness is constrained by insufficient barrier height and depth.
Contexto: El ruido vehicular urbano afecta la calidad ambiental y demanda soluciones basadas en infraestructura verde. Objetivo: Cuantificar la efectividad de barreras de Hibiscus rosa-sinensis L. en la reducción del ruido vehicular en la Avenida La Marina, Punchana, Iquitos, Perú. Metodología: Se desarrolló un estudio cuantitativo, aplicado, observacional, transversal y comparativo. La población estuvo constituida por barreras continuas de H. rosa-sinensis ubicadas entre la calzada y las edificaciones colindantes; la muestra fue no probabilística intencional de seis puntos distribuidos en los sectores EsSalud y Bellavista Nanay. Se aplicó observación técnica, medición acústica con sonómetro integrador Clase 1 conforme a IEC 61672-1:2013, calibración acústica IEC 60942:2017, ISO 1996-2:2017 y Protocolo MINAM. Se compararon tres posiciones: campo abierto, posición A y posición B. Resultados: Las barreras presentaron altura media de 1,208 ± 0,066 m y ancho de 1,008 ± 0,080 m. El LAeqT en campo abierto fue 74,63 ± 2,16 dB(A), superando el ECA en el 100 % de puntos. La posición A redujo 2,90 ± 1,05 dB(A), con diferencia significativa (U = 30,0; p = 0,033; r = 0,667), mientras la posición B no fue significativa (p = 0,120). Conclusiones: H. rosa-sinensis ofrece regulación acústica real, aunque limitada por altura y profundidad insuficientes.
