Temperature loads were taken according to standard EN and its Latvian National Annex. Therefore, a reserve of approximately 3–5 dB has to be taken into account when comparing the results with the limiting values. In this study, however, due to the wide range of possible input parameters, the wall panels without any leaks for sound (windows, doors, holes for ventilation, and connections with other structures) were considered. The required sound insulation of external walls R t r, s, w, including windows and doors corresponding to this range, is greater than 25 or 49 dB. Another limiting value can be derived from the Regulation, which provides requirements for sound insulation from environmental noise of 55 to 78 dB. However, actual environmental noise levels can be higher, because not all of the historical areas are built according to these regulations. There are maximum levels for allowable environment noise set by the Latvian Building Regulations, which are 50 to 65 dB, depending on the function of a particular area. The limits of sound reduction were evaluated according to the Latvian Building Regulations. Where R t r, s, w-sound insulation index R w-sound reduction (dB) C t r ( 100 − 3150 Hz )- correction for transport noise (dB). The obtained load-bearing capacity exceeded the design loads of a single-story family house by around 100 times, regardless of the degree of composite action. Structural analysis of the proposed wall panel was performed using non-linear finite element analysis software ATENA Science. To ensure sufficient sound insulation, the average thickness of the concrete wythes should be around 60 mm, preferably with a 15 mm difference between them. The minimum thermal insulation for family houses varies from 120 mm to 200 mm, depending on the material. The characteristics of the SW are compared to the requirements given in relevant European and Latvian standards. Regions with the lowest five-day mean air temperature of −20 ∘C were considered. The load-bearing capacities of composite and non-composite SWs are compared. In this study, a numerical investigation of structural, thermal and sound insulation performances was carried out. In almost no studies has sound insulation been evaluated. In most studies, relatively warm climatic regions are the focus, and thin-layer SWs with shear connectors to obtain a certain level of composite action are investigated. Other researchers have shown that SWs with thin wythes can be used as load bearing structures in low-rise buildings, thereby reducing the amount of concrete by 2–5 times if compared to conventional reinforced-concrete SWs.

The game features first-person exploration and combat, with players able to use “Tactical Time Dilation” to slow time down, as well as branching dialogue, a companion system, and setting heavily influenced by player decisions. The Outer Worlds originally launched for PC, PlayStation 4, and Xbox One in October 2019, with a Nintendo Switch version released in June 2020. In addition to the new story, the expansion includes new locations, new weapons and gear, a higher level cap, and new character perks and flaws. Olivia Ambrose, who was director of the project. Wealthy recluse Minnie Ambrose tasks them with finding answers regarding her mother, Dr. Peril on Gorgon takes players to the Gorgon Asteroid, the site of one of Halcyon colony’s more disastrous scientific endeavours, which is now overrun by monsters and other hostiles. A $24.99 Season Pass is also available, which will grant access to Peril on Gorgon as well as a second upcoming expansion. It will cost $14.99, with Xbox Game Pass subscribers receiving a 10% discount. Peril on Gorgon will launch on September 9, 2020, for PC, PlayStation 4, and Xbox One. Obsidian Entertainment and Private Division announced the first expansion for first-person sci-fi RPG The Outer Worlds.
