Recreational Noise Exposures at Motorsport Events

Noise induced hearing loss (NIHL) is a type of hearing loss that after repeated exposure to high levels of sound for extended periods of time can result in damage to the fragile structures of the inner ear. Hearing changes caused by NIHL could be temporary or permanent. Hazardous noise levels in the workplace environment have been known to cause NIHL over time. Therefore, governing agencies have noise standards that have been enacted to decrease the risk of developing NIHL in the workplace. The Occupational Safety and Health Administration, Mine Safety and Health Administration, and the Federal Railroad Administration are examples of these governing agencies. In addition, the National Institute for Occupational Safety and Health and the World Health Organization have provided best practice guidelines for prevention of NIHL by establishing permissible noise exposure criteria. Hazardous noise exposure is not only confined to the workplace but can be found in a variety of non-occupational settings including recreational activities. Occupational and non-occupational noise exposures are cumulative throughout a lifetime. However, there are no limits to reference for recreational exposures. Common recreational activities include target shooting, attending concerts, and attending motorsport or other sporting events among others. The motorsport industry is growing and includes countless aficionados partaking in motorsport events. Both recreational and occupational noise exposure studies have documented the risk for NIHL among individuals involved in motorsports. The range of sound pressure levels were between 63 dBA to over 100 dBA across studies investigating motorcycles, snowmobiles, stock cars, F1, monster trucks and tractor pulls (Bess & Poynor, 1974; Buhr-Lawler, 2017; Dolder et al., 2013; Jordan et al., 2004; Kardous & Morata, 2010; Moore, 2014; Morley et al., 1999; Rose et al., 2008; Ross, 1989; Van Campen et al., 2005). Hot rodding is a unique motorsport among other types that has not been evaluated for noise exposure of drivers, spectators, and event personnel. Due to an increasing number of individuals with NIHL, it is important that additional research is conducted to evaluate the noise exposures from motorsports that are contributing to this health issue. Development of prevention strategies and hearing conservation programs for individuals involved in motorsports is warranted. Recommendations for future directions and hearing health promotion activities targeting this population are provided. Audiologists can play a key role in the prevention of NIHL resulting from motorsport noise exposure by providing hearing conservation services, monitoring for auditory damage, and education for motorsport enthusiasts and employers

Exploring novel auditory displays for supporting accelerated skills acquisition and enhanced performance in motorsport

This paper explores the design, development and evaluation of a novel real-time auditory display system for accelerated racing driver skills acquisition. The auditory feedback provides concurrent sensory augmentation and performance feedback using a novel target matching design. Real-time, dynamic, tonal audio feedback representing lateral G-force (a proxy for tire slip) is delivered to one ear whilst a target lateral G-force value representing the ‘limit’ of the car, to which the driver aims to drive, is panned to the driver’s other ear; tonal match across both ears signifies that the ‘limit’ has been reached. An evaluation approach was established to measure the efficacy of the audio feedback in terms of performance, workload and drivers’ assessment of self-efficacy. A preliminary human subject study was conducted in a driving simulator environment. Initial results are encouraging, indicating that there is potential for performance gain and driver confidence enhancement based on the audio feedback

Crash Detection and Safety Shutoff Controller for Race Cars

This project involved the creation of a crash detection device for race cars, the DragAid-MK. The DragAid-MK is designed to provide safer racing conditions for drivers in the sportsmen category of drag racing. It was made to mount on any type of sportsmen racing vehicle and monitor g-force levels on the vehicle. When these levels become too great, the device will shut down the ignition system and fuel pump of the vehicle. It is hoped that the DragAid-MK will result in the elimination of the two main sources of ignition in racing accidents, making accidents safer for racers and rescue crews

Compilation of a Handbook for the Cal Poly Tractor Pull Team

This senior project discusses the compilation of a handbook for the Cal Poly Tractor Pull Team. The handbook was written to aid new team members and students in getting acquainted to the history of the motorsport, what is expected of a team member, standard operating procedures of equipment, and event operations. Results were obtained from a quiz administered to various persons. Responses showed ease of locating information as well as areas of potential improvement

Automobile Races and the Marketing of Places: A Geographic and Marketing Exploration of IndyCar Racing in the United States

IndyCar events attract thousands of spectators and over one million television viewers. Additionally, IndyCar is the most elite form of motorsport that races on oval speedways, natural terrain road courses, and temporary street circuits. This research utilizes case studies of IndyCar events contested on each of these three venue types (Iowa Corn Indy 250 – oval speedway; Indy 200 at Mid-Ohio – road course; Grand Prix of St. Petersburg – street circuit). Previous research in figurational sociology, place marketing, and mega-events provide a framework used to identify key similarities and differences among the perceived and observed benefits and costs of an IndyCar race on their host cities and regions. Identification and analysis of key local event stakeholders and sponsors from a content analysis of event souvenir programs, television broadcasts, and local newspaper coverage revealed key differences among the three case study events. Street circuit races rely on a high-level of public support, have a high impact on businesses and residents surrounding the venue, and can showcase a city’s downtown amenities via television exposure of city streets during most of the event. In the case of St. Petersburg, the festival atmosphere and high speed of IndyCar racing in their downtown streets has been part of a process of re-inventing the city as it sheds an image of a quiet city with mostly older residents and has been successful attracting both visitors and residents to downtown. Oval speedway events rely on high participation of private, local event sponsors that are marketing their good or service mostly to local race fans who, for the most part, stay only at the speedway on race day. In particular, the Iowa Corn Indy 250 provides a platform for local, corn-based ethanol promotion of their product in high-performance race cars. Road course races attract a greater number of weekend-long, on-site camping motorsport enthusiasts and participants as these events are more a celebration of the automobile industry, and in particular, the Honda assembly plants that employ thousands of nearby Ohio residents. The results from this research provide key lessons for other current and potential IndyCar venues across three different venue types
