Enhancing the efficiency of in-ear monitors for hearing-impaired musicians

Abstract

Some musicians are hearing impaired, some have finished their careers, but some continue to work, and it is much harder for them to be deaf than for musicians who are not. Some use hearing aids in their daily lives and use in-ear monitors in their live performances, which seem normal, but in their in-ears they only hear the metronome and drums. How can we improve the performance of in-ear monitors to near normal?

Objective

นักดนตรีบางคนที่พิการทางการได้ยิน บางคนจบอาชีพการงาน แต่บางคนยังคงทำงานต่อไปโดยที่หูหนวกนั้นยากกว่านักดนตรีปกติมาก บางคนใช้เครื่องช่วยฟังในชีวิตประจำวันและใช้เครื่องช่วยฟังแบบอินเอียร์ในการแสดง สดซึ่งดูเหมือนปกติ แต่ในอินเอียร์ของพวกเขา ได้ยินเพียงเครื่องเมตรอนอมและกลองเท่านั้น ถ้าพวกเขาสามารถใช้อินเอียร์มอนิเตอร์ในการทำงานได้แต่ยังไม่สามารถทำได้อย่างเต็มประสิทธิภำพเกิดจากอะไรและแก้ไขอย่างไร

Attributes prediction of biocomposite scaffold made from 3D printing using a finite element analysis

Bone tissue scaffolds are made from biomaterials that support rapid repair and healing. Scaffold fabricators have produced materials that are able to degrade a biosystem or human body excellently. Thus, this work aims to study the optimization of materials, shape, and the 3D printing process with FDM. Finite element analysis is also used to predict mechanical properties of the scaffold and find the optimal shape and pore size. However, the materials studied include PLA, PCL, and HA.

WHAT IS THE CURRENT ENERGY EXPENDITURE OF HOUSEHOLDS IN THAILAND ?

The purpose of this study was to examine and analyze the factors influencing household energy expenditures in Thailand. With sample group of 57,600 households. The findings reveal that the majority of the sample population is male, with an average age of 54.31 years, and most are married. The majority have an education level of primary or secondary school and are primarily Own-account worker (without employee), Private company employee or engaged in other job. In terms of social characteristics, the average household size is 2.71 people. Most residences are located in the Central, Northeastern, and Northern regions with similar proportions, followed by the Southern region and Bangkok, respectively. Most type of dwelling in detached houses, with materials of construction being cement or brick, followed by half concrete and wood. Regarding tenure, almost own dwelling and land, with an average of 2.88 rooms per household. Electricity is available in all households, with an average of 2.30 vehicles per household and an average of 22 electrical appliances per household. Regarding economic characteristics, most respondents have government/state enterprise welfare and receive benefits from the government programs. The majority have never borrow money from government funds. The average communication services of respondents amount to 788.46 THB, while the average household debt stands at 4,760.74 THB. At a significance level of 0.05, the factors influencing household energy expenditures in Thailand include gender, education level, marital status, job, household size, residential region, type of dwelling, material of construction, tenure, number of rooms, number of vehicles, number of electrical appliances, welfare of medical services, receive benefits from the government programs, borrow money from government funds, communication services, and household debt. However, age does not affect household energy expenditures in Thailand. The results of multiple linear regression analysis indicate that six quantitative independent variables—communication services, number of household electrical appliances, number of vehicles in the household, household debt, number of rooms, and household size—explain variations in household energy expenditures, with an Adjusted R Square value of 0.561.

Smart Jaundice Diagnostic System

Jaundice, a common condition in infants that results from high bilirubin levels in the blood, often requires early diagnosis and monitoring to prevent severe complications, especially in newborns. Traditional diagnostic methods can be time-consuming and subject to human error. This study proposes an approach for real-time jaundice detection using advanced image processing techniques and machine learning algorithms. By analyzing images captured in RGB color spaces, pixel values are extracted and processed through Otsu’s thresholding and morphological operations to detect color patterns indicative of jaundice. A classifier model is then trained to distinguish between normal and jaundiced conditions, offering an automated, accurate, and efficient diagnostic tool. The system’s potential to operate in real-time makes it particularly suited for clinical settings, providing healthcare professionals with timely insights to improve patient outcomes. The proposed method represents a significant innovation in healthcare, combining artificial intelligence and medical imaging to enhance the early detection and management of jaundice, reducing reliance on manual interventions and improving overall healthcare delivery.
