The solution is obtained by solving a set of algebraic equations with only three unknown parameters, and the method can easily be extended to obtain approximate solutions to vibration problems for any type of non-uniform beam. The proposed AMDM is used to analyze the vibration of beams using a recursive approach. The discontinuity can stem from a geometric change in the beam cross-section, a sudden material change within the beam or a sudden change in foundation material properties. The relatively efficient and accurate Adomian modified decomposition method (AMDM) is used in this paper to investigate the free vibrations of Euler-Bernoulli beams, with a single section discontinuity present, and resting on a two-parameter elastic foundation. Nevertheless, further research should clearly take age into account, and collapsing soundscape evaluations across age groups is certainly not supported by these findings. From this comparison, no hard conclusions can be drawn because different participants have been questioned at each site and there might be other underlying confounders steering these results. Conversely, for a younger population, a quiet area could be too quiet. It could be hypothesized that especially in poorer soundscapes, age becomes a more important factor in perceived quality. For site 2, however, increasing age had a stronger effect, such that people rated the soundscape significantly louder, more chaotic, less calm, and less appropriate. At site 1, only monotonous decreased with increasing age. For both sites, and in line with the literature, noise sensitivity increased significantly with age. In terms of the sound environment, site 1 was more shielded from road traffic while site 2 was next to a relatively busy city road mean pleasantness across all participants was rated as 4.5! and 3.1!, respectively, on a 5-point scale. The fraction of participants younger than 30 was 60~% at site 1, and 51~% at site 2, however, age distribution did not differ significantly between the two sites. Participants were asked to rate the soundscape in terms of eight well-known soundscape indicators (SSQP) including pleasant, chaotic, and vibrant, along with reporting the perceived loudness and soundscape appropriateness, their noise sensitivity, and age. The present study used an on-site questionnaire to measure the perceived quality of two different newly designed urban spaces (N = 103 and 438, respectively), which was analyzed as a function of participants' age. And yet, age is not systematically considered when designing and evaluating urban soundscapes.

While the war continues on, Ukraine is still in dire need of support. With the help of nearly 1000 audience members, and several hundred more who tuned in online, the benefit successfully raised over $34,000 in one day! You can watch the 4.5hr long concert, featuring 55 local musicians here. The photo above is from the “With Ukraine” Benefit Concert (March 11, 2022), organized by a collective of local artists and musicians who came together the day after the invasion began (more info here), with the goal of raising awareness about the invasion, sharing Ukrainian culture, and raising funds to purchase humanitarian, military and other aid for Ukraine. We are devastated by the unprovoked Russian invasion of Ukraine, and are working tirelessly both together and separately to help Ukraine in any way we can. Did you know that all three members of BLISK have Ukrainian roots? Nastasia Y was born in Ukraine, Stephania was born into the Ukrainian-Canadian diaspora, and Ekaterina has some Ukrainian ancestry.
