“…Hearing function assessment through pure-tone audiometry has revealed abnormal thresholds at higher frequencies among similar participants (above 8 to 16 kHz) [2]. Studies by Jadia et al [3], Hegde et al [8], Callejo et al [9], and others highlighted sensorineural hearing loss in mobile phone users compared to non-users. Our research discerned variations in bone conduction thresholds, air conduction thresholds, and air-bone gaps, revealing noteworthy distinctions between dominant and non-dominant ears, albeit without reaching statistical significance.…”

“…As an illustrative instance, in the context of OAE, eight participants manifested the absence of OAE in the non-dominant ear, resulting in a non-statistically significant p-value of 0.1729, as determined by the Chi-square test. Similarly, the examination of the relationship between the duration of mobile phone usage and the absence of OAE yielded a non-statistically significant p-value of 0.410656, determined through the Chi-square test [3,[8][9][10][11]. On similar lines, Ramya et al [10] also found that there was a significant increase in the hearing thresholds at all frequencies for air conduction and bone conduction in the right ear (test group) compared with the control group.…”

BackgroundIndia has approximately 1.02 billion mobile phone users. The electromagnetic radiations emitted by telecommunication systems are absorbed by the recipient's body, leading to changes in brain electrical activity, sensations of warmth or burning around the ear, and alterations in the blood-brain barrier. The inner ear, being the closest organ during mobile phone use, directly receives these electromagnetic radiations. This study aims to assess the inner ear function among mobile phone users, investigate the impact of mobile phones on the hearing thresholds of volunteers through pure-tone audiometry (PTA), and delve into the same using otoacoustic emissions (OAE).

“…The ear, being in close relation with the mobile phone, is at high risk because of electromagnetic radio waves. 13 There is a hypothesis that the usage of mobile phones is known to cause acoustic neuroma. 14 15 Long-term exposure to electromagnetic fields produced by mobile phones has been shown to cause hearing loss at the cochlear level.…”

Objective The prolonged exposure to electromagnetic fields of mobile phones can damage the cochlear hair cells, which can be detected by otoacoustic emission (OAE). To know the effect of mobile phones on hearing, the young volunteers were subjected to prolonged mobile phone usage and changes in OAE were recorded. Materials and Methods Twenty-eight volunteers with normal hearing were made to talk one full hour continuously on the mobile phone. Distortion product otoacoustic emission (DPOAE) was measured prior to the usage of mobile phones and immediately after the use (post-exposure 1) and 24 hours after the use (post-exposure 2). The values were compared. Results Out of the 28 volunteers, 20 were females and 8 were males. Twenty-one volunteers preferred the right ear while using mobile phones, 7 preferred the left ear. There was no statistically significant difference between the baseline DPOAE values and values of post-exposure 1 and 2 when only the preferred ear was taken into consideration. When the preferred ear was compared with nonpreferred ear, a statistically significant difference was found only in the low frequencies between the pre-exposure and post-exposure 1 values. Conclusion This study shows there was no significant correlation between OAE and prolonged mobile phone exposure when the preferred ear was not considered.

“…As diferenças de intensidades entre as orelhas, neste estudo, variam de 4,3 a 9 dB, o que representa uma sensibilidade até praticamente três vezes maior para uma orelha em relação à outra (16,18) . Apesar dos limiares tonais poderem ser percebidos com diferenças mínimas de 0,5 dB (9) , diversos autores em seus estudos utilizaram diferenças entre limiares das orelhas de até 10 dB (3)(4) .…”

“…Portanto, para expressar coeficientes de pressão em decibel, a fórmula poderá ser escrita da seguinte maneira: ou Para minimizar a interferência das assimetrias interaurais, estudos que envolvem a localização de fontes sonoras, de um modo geral, estabelecem um valor máximo de 10 dB entre os limiares auditivos das duas orelhas, a exemplo de trabalhos anteriores (17) . Entretanto, sabe-se que diferenças de 6 dB já representam uma sensibilidade duas vezes maior para uma orelha em relação à outra (16,18) e 10 dB, aproximadamente dez vezes, o que, teoricamente, poderá dificultar a localização por DII.…”

OBJETIVO: Esclarecer a relação das diferenças entre os limiares auditivos das orelhas direita e esquerda com o percentual de erros e acertos na localização de fontes sonoras em ambientes reverberantes. MÉTODOS: Foram examinados 56 voluntários, sendo 33 homens e 23 mulheres, média de idade de 26,6 anos, submetidos aos seguintes testes: otoscopia, audiometria tonal, imitanciometria e emissões otoacústicas. Todos os voluntários apresentaram audição dentro dos padrões de normalidade. Posteriormente, os indivíduos foram submetidos ao teste de localização sonora espacial, onde foram utilizadas ondas quadradas com freqüências fundamentais centradas em 500 Hz, 2000 Hz e 4000 Hz. Os estímulos foram apresentados quinze vezes em cada uma das treze posições espaciais do aparelho utilizado, em cada uma das freqüências escolhidas. Assim, foram apresentados 585 estímulos, no total, por pessoa. RESULTADOS: Na amostra estudada, encontrou-se como resultado, idade entre 18 e 50 anos, média da diferença dos limiares auditivos entre as orelhas de 6,81 dB e percentual de acertos na localização sonora dentro dos padrões normais. A correlação entre as diferenças interaurais e os acertos na localização, no entanto, não foi significativa. CONCLUSÕES: O presente estudo demonstrou que, em pessoas com audição normal, as variações dos limiares auditivos e as diferenças entre as orelhas até 10 dB não interferem na localização de fontes sonoras.
