“…2 ). In addition, although wearing a helmet worsens hearing to a signifi cantly greater extent than wearing a cap in this study, hearing thresholds exceeded neither with cap nor with helmet a value of 20 dB HL and are therefore still within the range of normal hearing (i. e., hearing thresholds not greater than 20 dB HL at any frequency) [ 9 ] . Thus, we conclude that both the cap and the helmet attenuate sounds only slightly.…”

“…Regardless of their minor impact on the attenuation of sounds a statistically signifi cant diff erence between cap and helmet has been found. Kieran et al [ 9 ] investigated the eff ect of head protection on the hearing of rugby players. These authors found that neither the application of adhesive tape ("ear taping") nor wearing a scrum cap showed a signifi cant drop in hearing threshold [ 9 ] .…”

Effect of Wearing a Ski Helmet on Perception and Localization of Sounds

Helmet use on ski slopes has steadily increased worldwide over the past years. A common reason reported for helmet non-use, however, is impaired hearing. Therefore, an intra-subject design study was conducted to compare hearing thresholds and sound source localization of 21 adults with normal hearing in an anechoic chamber when wearing a ski helmet and ski goggles or wearing a ski cap and ski goggles to the condition head bare. Hearing thresholds while wearing a ski helmet (6.8 ± 1.6 dB HL) and ski cap (5.5 ± 1.6 dB HL) were significantly different (p = 0.030, d = 0.44). Compared to head bare (2.5 ± 1.2 dB HL), a significant difference was found for the ski helmet only (p = 0.040, d = 1.57). Regarding sound source localization, correct scores in the condition head bare (90%) showed a highly significant difference compared with those of condition cap (65%) and helmet (58%), respectively (p < 0.001; d > 2.5). Compared to the ski cap, wearing the helmet significantly reduced correct scores (p = 0.020, d = 0.59) irrespective of the tested sound pressure levels. In conclusion, wearing a ski helmet impairs hearing to a small though significantly greater extent compared with a cap, the degree, however, being less than what is termed as a hearing impairment. Compared to the condition head bare, wearing a ski cap or a ski helmet significantly reduced one's ability of sound source localization.

Objectives: The aim of the study was to investigate whether a ski helmet interferes with the sound localization and the time of sound perception in the frontal plane. Material and Methods: Twenty-three participants (age 30.7±10.2) were tested on the slope in 2 conditions, with and without wearing the ski helmet, by 6 different spatially distributed sound stimuli per each condition. Each of the subjects had to react when hearing the sound as soon as possible and to signalize the correct side of the sound arrival. Results: The results showed a significant difference in the ability to localize the specific ski sounds; 72.5±15.6% of correct answers without a helmet vs. 61.3±16.2% with a helmet (p < 0.01). However, the performance on this test did not depend on whether they were used to wearing a helmet (p = 0.89). In identifying the timing, at which the sound was firstly perceived, the results were also in favor of the subjects not wearing a helmet. The subjects reported hearing the ski sound clues at 73.4±5.56 m without a helmet vs. 60.29±6.34 m with a helmet (p < 0.001). In that case the results did depend on previously used helmets (p < 0.05), meaning that that regular usage of helmets might help to diminish the attenuation of the sound identification that occurs because of the helmets. Conclusions: Ski helmets might limit the ability of a skier to localize the direction of the sounds of danger and might interfere with the moment, in which the sound is firstly heard.

“…Players also claimed that headgear made them feel too hot during the games and too tight while wearing close fitting headgear [5]. Disturbance to hearing senses is another limitation faced by players who wear headgear, makes them unable to hear the instruction from the captain or teammates [6]. There were studies that investigated the effect of the protective equipment in preventing injury such as headgear used in rugby union and the result shows that it is only capable to provide limited protection and decrease on the risk of injuries.…”

Rugby headgear is one of the important protective tool for protecting rugby players from head injury. However, there are still some professional or amateur rugby players who are not concerned about the use of headgear as a protective device. Rugby headgear has been created to protect the heads of rugby players in particular to avoid minor injuries such as wounds because rugby is a sport that requires strong physical movements and abusive techniques. At the same time, the ability of rugby headgear to protect against the occurrence of brain injury is questionable. Therefore, the objective of this project is to propose a conceptual design of rugby headgear by taking into account factors to prevent or reduce the potential of brain injury. The methodology used was a survey of professional and amateur rugby players to determine the need for the design of the headgear, conceptual map for the idea of development, House of Quality (HoQ) in assessing the needs of rugby players, Morphological Chart in determining the concept, Pugh's Selection Method in finding the most appropriate design. Headgear that is round and cover most of the heads has been selected as a conceptual design with sorbothane as core material. Valco strap was used as fastener and sponge in the head for the comfort to the player’s head

Abstract: Theoretical concerns that "ear taping" and scrum caps affect hearing of rugby players are unfounded and should not discourage their use.
