Cardiovascular and stress responses to short-term noise exposures—A panel study in healthy males

Abstract

Background While previous epidemiological studies report adverse effects of long-term noise exposure on cardiovascular health, the mechanisms responsible for these effects are unclear. We sought to elucidate the cardiovascular and stress response to short-term, low (31.5-125 Hz) and high (500 – 2000 Hz) frequency noise exposures. Methods Healthy male (n = 10) participants were monitored on multiple visits during no noise, low- or high-frequency noise exposure scenarios lasting 40 minutes. Participants were fitted with an ambulatory electrocardiogram (ECG) and blood pressure measures and saliva samples were taken before, during and after noise exposures. ECGs were processed for measures of heart rate variability (HRV): high-frequency power (HF), low-frequency power (LF), the root of the mean squared difference between adjacent normal heart beats (N-N) intervals (RMSSD), and the standard deviation of N-N intervals (SDNN). Systolic blood pressure (SBP), diastolic blood pressure (DPB), and pulse were reported and saliva was analyzed for salivary cortisol and amylase. Multivariate mixed-effects linear regression models adjusted for age were used to identify statistically significant difference in outcomes by no noise, during noise or after noise exposure periods and whether this differed by noise frequency. Results A total of 658, 205, and 122, HRV, saliva,and blood pressure measurements were performed over 41 person days. Reductions in HRV (LF and RMSSD) were observed during noise exposure (a reduction of 19%(−35,−3.5) and 9.1%(−17,−1.1), respectively). After adjusting for noise frequency, during low frequency noise exposure, HF, LF, and SDNN were reduced (a reduction of 32%(−57,−6.2), 34%(−52,−15), and 16%(−26,−6.1), respectively and during high frequency noise exposure, a 21%(−39,−2.3) reduction in LF, as compared to during no noise exposure was found. No significant (p>0.05) changes in blood pressure,salivary cortisol or amylase were observed. Conclusions These results suggest that exposure to noise, and in particular, to low-frequency noise negatively impacts HRV. The frequencies of noise should be considered when evaluating the cardiovascular health impacts of exposure.

The acute effect of exposure to noise on cardiovascular parameters in young adults

“…Accordingly, noise B caused minimal physical responses in experimental subjects. In line with our results, Walker et al 47) tested the cardiovascular and stress responses to short-term exposures to low (31.5-125 Hz) and high (500-2000 Hz) frequency noises at 75 dBA, and found no significant (p< 0.05) changes in blood pressure. These results suggest that noise exposure negatively impacts blood pressure, especially when high-frequency noises are involved.…”

Different Types of Sounds and Their Relationship With the Electrocardiographic Signals and the Cardiovascular System – Review

“…HRV (HF and LF/HF) changes with both sound ( Nardelli et al, 2015 ; Nozaki et al, 2015 ; Watanabe et al, 2015 ; Ishimitsu et al, 2017 ) and noise ( Lee et al, 2010 ; Kraus et al, 2013 ; Oh et al, 2015 ; Gallasch et al, 2016 ; Walker et al, 2016 ; El Aarbaoui et al, 2017 ) stimuli, whereas GSR changes with sound ( Martin-Soelch et al, 2006 ; Bidin et al, 2016 ) and musical ( Wagner et al, 2005 ; Kim and André, 2008 ; Goshvarpour et al, 2016a ) stimuli. Moreover, LF also showed changes with exposure to noise ( Lee et al, 2010 ; Cho et al, 2011 ; Kraus et al, 2013 ; Oh et al, 2015 ; Walker et al, 2016 ; El Aarbaoui et al, 2017 ). Here, it is important to note that both sound and musical stimuli can affect memory and emotions.…”

“…Samples are also used with a combination of males and females ( Martin-Soelch et al, 2006 ; Björ et al, 2007 ; Koelsch et al, 2007 ; Lee et al, 2010 ; Orini et al, 2010 ; Kraus et al, 2013 ; Naji et al, 2014b ; da Silva and Backs, 2015 ; Nozaki et al, 2015 ; Bidin et al, 2016 ; El Aarbaoui et al, 2017 ; Goshvarpour et al, 2017 ). There were few studies with just males ( Tomei et al, 2000 ; Cho et al, 2011 ; Gupta and Gupta, 2015 ; Walker et al, 2016 ) or just females ( Binns-Turner et al, 2011 ; Rhomberg et al, 2014 ; Nakajima et al, 2016 ; Abedi et al, 2017 ). With respect to the sample size, many of the studies used a size between 20 and 33 ( Holand et al, 1999 ; Thayer and Faith, 2001 ; Chang et al, 2004 ; Martin-Soelch et al, 2006 ; Björ et al, 2007 ; Kasprzak, 2010 ; Krantz et al, 2010 ; Binns-Turner et al, 2011 ; Cho et al, 2011 ; Dousty et al, 2011 ; Croy et al, 2013 ; Naji et al, 2014b ; Pérez-Lloret et al, 2014 ; Nardelli et al, 2015 ; Nozaki et al, 2015 ; Al-Galal et al, 2016 ; Abedi et al, 2017 ) or 35 and 88 ( Tomei et al, 2000 ; Kenntner-Mabiala et al, 2007 ; Koelsch et al, 2007 ; Raggam et al, 2007 ; Graham et al, 2009 ; Orini et al, 2010 ; Sancini et al, 2012 ; Rhomberg et al, 2014 ; Gruhlke et al, 2015 ; Gupta and Gupta, 2015 ; Hajizadeh et al, 2015 ; Krabs et al, 2015 ; Sim et al, 2015 ; Watanabe et al, 2015 ; Gallasch et al, 2016 ; Goshvarpour et al, 2016a ,...…”
